To best understand them, and why they matter, you must first understand what ASHRAE is.

ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, describes itself as “a global society dedicated to advancing human well-being through sustainable technology for the built environment.” This includes building systems, energy efficiency, indoor air quality and sustainability and covers everything from residential and personal vehicle HVAC systems to those in commercial airplanes and, of course, scientific laboratories. Its history dates back to 1894, making it trusted as one of the premier sources for standards, operating practices, research and more within the industry.

One of ASHRAE’s main purposes is to create and publish standards for testing and performance criteria regarding the design and maintenance of indoor environments. Their standards create defined minimum values for accepted performance of a variety of ventilation-related products.

ASHRAE 110 Procedure

ASHRAE Standard 110, or simply ASHRAE 110, explains a method for testing the performance of laboratory fume hoods. Essentially, it outlines a quantitative test procedure for determining the operating capabilities, such as containing and exhausting fumes, of a fume hood. The ASHRAE performance test does not, however, directly correlate to safety of the hood operator. This is due to the large number of variables in hood environment (e.g. cross drafts, hood location or temperature), hood use, and materials in the hood.

ASHRAE 110 has become the standard for testing fume hood containment since its inception in 1985. It is used not only by manufacturers during development and design, but also as an informal criteria for purchasing a fume hood for many labs, and as a method of performance evaluation and certification for fume hoods being installed. It can even be used as a diagnostic tool to identify problems in an existing fume hood/HVAC system installation.

There are three key areas of the standard: face velocity measurement, smoke visualization, and tracer gas containment.

The face velocity measurement requires multiple point readings to determine the average face velocity the fume hood can maintain. It also includes measurement of cross drafts around the hood and calibration of airflow monitors.

The smoke visualization test has procedures for both small volumes and large volumes of smoke to clearly see how the air moves and is contained within the hood. In addition to airflow patterns, the smoke test shows turbulence at the front of the hood caused by the room environment. It can also show how conaminants could escape from the hood, if it is leaking, and reach the operator at various sash heights.

The tracer gas containment testing determines exposure levels based on how many contaminated particles are able to escape the hood and reach the operator's breathing zone. This procedure involves three “static” tests, sash movement effect measurement test, and a perimeter scan. The latter two are optional.

The static placements are three set locations for the ejector, directly in the center of the work surface and 12” in from each side toward the center of the hood. Sulfur hexafluoride (SF6) gas is put into the hood through the ejector and then gas analyzers on a mannequin placed at the average height of an operator’s face, known as the “breathing zone,” measure the amount of SF6 in five minute intervals to determine the average escape amount. Three of these tests are done. Each one lasts five minutes and uses four liters per minute of SF6. ASHRAE suggests measuring concentration to 0.01 parts per million (ppm). Labconco uses analyzers that measure to 0.000 ppm for precise understanding of the hood’s containment capability.

The use of SF6 is important due to its uniqueness. Since it is not commonly found in labs, it’s not likely for the sensor to detect it from the environment. Furthermore, it is five times heavier than air so it’s very clearly the gas from the hood during the test. It also behaves consistently so the same test can be run multiple times to reliably get the same result. These unique attributes help to avoid false readings during the test.

ASHRAE 110 Tests

There are three test types, As Manufactured (AM), As Installed (AI) and As Used (AU). AM is done once the hood is built and is generally done in a testing lab where environmental factors are removed as much as possible. AI testing is done once the hood is installed in the lab but before anything is placed inside. This can reveal issues related to how the hood was installed, room operation/location, and other room environment factors. Finally, AU testing is done in the lab with materials (beakers, equipment, etc.) inside the hood. This test takes into account both the room environment and users, and can determine if there is an issue with how it is being operated by comparing the test results to the AI results.

ASHRAE’s goal is for health and safety officers, lab managers and lab technicians to understand the operation of the hood and the safety of it. ASHRAE will not, however, provide a recommendation for the test results. Each lab sets its own acceptable levels for the test results. In addition, some organizations, such as the Scientific Equipment and Furniture Association (SEFA) provide ratings for acceptable concentration levels of each test. For example, SEFA requires a hood to have an average containment loss of 0.05 ppm or less when tested at four liters per minute of tracer gas used in the AM test, and an average of 0.10 ppm or less for the AI and AU tests, in order to receive the SEFA designation of a low velocity/high performance fume hood.

ASHRAE 110-2016

An updated ASHRAE 110 was approved in April 2016, replacing the previous version from 1995. The latest version includes changes regarding the mannequin height and data collection. The test procedure itself was modified based on committee experience and to clarify statements from the 1995 edition, such as the breathing zone height.

Labconco’s very own Kevin Gilkison, Vice President of Sales Engineering, is one of the co-writers of the standard. He explained the major changes of this update.

The location of the breathing zone was lowered to 22” from the work surface. This was based on research suggesting that the average height of fume hood operators has decreased over the past decade. Gilkison shared this change is particularly important because it creates a more accurate test and therefore can lead to a safer work environment for the operator.

Another key component of the update is that it requires digital collection of data during testing procedures rather than manual data collection. This was previously recommended, but not required. According to Gilkison, this reduces the chance of human error in recording this data. The information-based sections were also significantly lengthened, including expansion of Appendix A and a new, non-mandatory Appendix B that provides guidance on investigating poor fume hood performance.

<![CDATA[Real lab efficiency vs. pipe dreams]]>http://www.labconco.com/news/real-lab-efficiency All too often doing the right thing is unrealistic. Cutting down on wasted energy, wasted time or wasted water would be great, but when it requires a brand new laboratory or a full redesign of your lab space, obtaining the resources to get it done can seem like a Herculean task. 

Refreshingly, this article by Jessica Burdg gives you several smaller, more feasible projects that you can undertake to make your lab less costly and more productive. Some of these suggestions can save hours of wasted time so you can get on to more profitable projects. Others can cut down on your lab's overhead by reducing energy consumption.

Did you realize that using the wrong kind of biosafety cabinet, for instance, can turn an otherwise innocuous procedure into a major drain on the lab's energy bill? Or that washing pipettes with certain popular types of equipment uses 50 times more water than necessary?

Today’s laboratories are hotbeds of innovation, harborers of cutting-edge research and homes of state-of-the-art scientific equipment. They also use a staggering amount of energy in the process, consuming up to five times more energy per square foot than office buildings. The water usage statistics show a similar trend, as labs in university settings in particular often boast some of the highest water consumption figures on campus. What is the root of this struggle?

With a host of strict ventilation requirements, constantly running equipment and no shortage of applications that require water, it’s easy to see why maximizing efficiency in labs has become a priority. Some sustainability-focused organizations, including the U.S. Green Building Council, are promoting change in how buildings like laboratories are constructed, offering incentivized green building certification programs such as Leadership in Energy and Environmental Design (LEED). LEED rankings include...

<![CDATA[Labconco's caring spirit makes it Christmas in October]]>http://www.labconco.com/news/labconcos-caring-spirit-makes-it-christmas-in-oc

When 25 Labconco associates and family members converged on our adopted home just a few miles from Labconco corporate headquarters on Saturday, October 1, 2016, the sunny, warm weather, could not have been a more appropriate metaphor for the feeling of doing something good for our community. We came together to help Ron, a 74-year old veteran who was living alone when he broke his ankle and required prolonged hospital care. His home needed help he couldn’t physically accomplish nor financially afford.

Labconco people care. We volunteer and give back to our hometown because we know being good neighbors makes a difference in our community. Christmas in October is just one heartwarming example. Since 1991 and every year since, Labconco associates have participated in this worthy cause.

This Kansas City volunteer organization, started 33 years ago, has allowed needy families, the elderly, the disabled and veterans live in safety, warmth and dignity. Through its Adopt-A-House program, Christmas in October rehabilitates 350-400 homes every year.

Labconco associates and their families helping a community member

Mark Schmitz, our Christmas in October leader for several years, made all the preparations before the big day. Throughout the summer while Ron was hospitalized, Mark put his engineering expertise to work as he inspected the home for needed repairs. A new ramp to the front door, yard clean up, rotted trim replacement and house painting topped the list. Mark and his son Matthew spent a day building a ramp to Ron’s front door. Then the home was now ready for us to do the rest.

Many hands make light work. Our team cleaned the gutters, repaired the back stoop, scraped and painted the faded house, and removed excess foliage. Labconco associate Lesley McMillin commented, “It’s fun getting to know my co-workers better. And with such a big group working, it is great to see such a huge improvement in a short period of time for a person who needs it.”

Kevin Conley agreed. “Doing something good for our neighbors and being with my colleagues outside of work are what keeps me coming back every year.”

Labconco teaming up for Christmas in October 2016

After his first year working at Christmas in October, Scott Hamm added, “It was well organized and supported. I had a blast working on the house knowing that we were helping someone who truly needed it. When we finished, you could clearly see the results. It had a huge impact on the structure and surrounding environment.”

In the end, we provided an attractive home for the neighborhood and a safer home for Ron, while we left with a feeling of accomplishment and happy hearts. I’m ready for next year.

<![CDATA[Does lab equipment longevity really matter?]]>http://www.labconco.com/news/does-lab-equipment-longevity-really-matter The purpose of some laboratory equipment is relatively straightforward. Like many of our competitors, the products in our catalog offer protection for personnel, products, and environments as required by application and to make laboratory spaces more versatile and efficient.

There's something else, though—something Labconco has not forgotten in all our 91 years of engineering and manufacturing the products that fill university teaching labs, forensic science facilities, clean rooms and more: Science is about people, and our job is to empower those people with the tools they need to excel. You see, it's not just about our work—it's about the important work of our extended family of customers.

We take this responsibility seriously, which is why we've long been committed to a manufacturing process that prioritizes quality. In many cases, our equipment even becomes obsolete before it fails. Take, for instance, one scientist’s experience with a laboratory cart that even outlasted its facility and found a new home in an old friend’s shop. We’re talking about Gene McGough, and you can read his story here: Laboratory Cart 604: A Love Story.

Lyophilizer Longevity

Laboratory carts aren't our only products that have long lives—not by a long shot. For example, in 2013, we set out in search of the oldest, still functional freeze dryer so we could learn its story (and offer its home lab a new FreeZone® Freeze Dryer, glassware credit, PrimeMate™ Oil Change System, and Mini Stoppering Chamber for humoring us). We were most impressed by the winning submission below from Mr. Kush Shah from Texas A&M. The unit was so old that we could no longer track the serial number, but Mr. Shah was still pleased with its operation.

"Our freeze dryer has been well maintained with pride and care by our lab members and operates perfectly... We will use the newly acquired equipment to perform cutting edge research in the field of nanotechnology and drug delivery," he told us.

There were numerous entries that received honorable mention, such as the one submitted by Sushma Trehan of Physical Optics Corp.

"I have used Labconco Freeze Dryers 'til they go obsolete. I want to use them 'til I go obsolete. I still have a few productive years left," she shared with us.

Final Thoughts

Now, there certainly are instances when antique lab equipment is simply too old to use, especially when containment is of utmost importance. All in all, though, we’re just glad that when we say you can count on us, you know that we can offer you equipment that will honor our word. That’s a very good feeling.

<![CDATA[Laboratory Cart 604: A Love Story]]>http://www.labconco.com/news/laboratory-cart-604-a-love-story In December of 1957, Gene McGough was interviewing for his job in a laboratory at the former Potash Company of America (PCA). A Labconco laboratory cart labeled 604 sat next to him, laden with 500 mL flasks. He got the job. Six months later, Gene bought a Jaguar XK-150. Two weeks after that, he was married—another love story for another time.

Gene used Cart 604 throughout his six-year stint with PCA, often logging his hours with the cart by his side and the car in the lot. He eventually moved on to other career opportunities. Still, when he heard PCA had closed their operations and had plans to demolish his old laboratory, he knew he had to go back and rescue what he could.

Gene managed to save Cart 604 along with some other antique items. Cart 604, though, wasn’t built to collect dust. Neither was Gene.

Cart 604 has seen better days

After he lubricated the casters and removed the side rails for cleaning, he spent two weeks on a mission of trial and error to find the correct positions for each of Cart 604’s pieces. Because the holes were individually hand-drilled, each rail was unique. He was successful.

Both Gene and Cart 604 continue to work to this day—only this time, they have a new project. Gene’s rescued, mostly-original Cart 604 now sits in his workshop, holding tools to help him restore his truly antique, powder blue Jaguar.

Gene reports Cart 604 has survived the years better than his beloved car. But if his history of successful restoration is any indication, that Jaguar is sure to be purring in no time.

<![CDATA[Racing and Curing: Labconco's Race for the Cure Tradition]]>http://www.labconco.com/news/racing-and-curing-labconcos-race-for-the-cure-tr What does tradition feel like? I’ve come to the age where I think a lot about traditions in my life… the things that my parents, my sisters and I ALWAYS did when I was a kid, those things that built anticipation when I knew the calendar was closing in, the memories that remained afterwards, the joy we share now talking about those times in the past. I think about things my own family does now that I hope are creating joyous memories for my own children.

I think about participating in the Race for the Cure as part of the Labconco Team over the past 5-6 years and what an absolute treasure chest of memories it holds for me. I’m blessed to be part of a company who values giving back to our community and also fosters a way for those of us who desire to do so, the ability to work together as a team in that act of giving back. Whether the Labconco Team is running in the race or working at the water station to serve H2O to weary runners, we are doing it together, as a team, just like everything else we do at Labconco. 

What a rush. What a ride. What a thrill. What a joy. What a pleasure it is to work with such great people every day and then hang out with them on an early Sunday morning to set up Water Station #3.

Diane Williamson, our unwavering leader for this event every year since we started participating, had us whipped into shape bright and early. Our station was set up, cups arranged, laid out, prepped, filled and layered with ample time to spare. She has turned this into a world-class serving system and conducts herself with class and grace, just like she does with our customers each and every day. 

Every Labconco team member who was there that morning served the racers with the same level of highest-tier service that I witness every day in our office environment as they go about serving our “paying customers.” You could hear it in their voices as they evaluated the race route on the map, as they tried to determine the best way to lay out the serving tables and the best places for us to stand to get the most water to the most runners in the least amount of time—without hampering the stride and pace of the runners. They even evaluated the optimal way to lay out the trash bins to leave the smallest amount of litter on the streets after we were done.

I’m thrilled just to have been there and to be part of a group of people who are truly there to serve to the best of their ability. It is more than just “Meh, I’m here to toss some cups of water at people.” They are there to give from their heart… above and beyond.

You never know what you’re going to get when it comes to race day weather. Welcome to the Midwest. We’ve had race mornings that were cold and rainy (which makes it very hard to give away water, let me tell you from experience), and mornings like we had this year, when we are a bit on the warmer side… with a water station on the sunny side of the race route, on the incline of a hill. I guess that made us the luckiest water station on the route because we were everyone’s best friends that morning. They were all glad to see us and very glad to accept our cups of dihydrogen monoxide.

Once the race kicks into high gear and the pace runners have zoomed past us at their 4-minute mile pace, the masses of people start to descend upon us and it really starts hopping. It’s amazing how quickly 10,000 people can go by, but it is so fun to engage with the runners, have fun with them as they enjoy race day and the costumes that dot the race route, cheer with those who cheer, chant with those who chant, sing with those who sing. We didn’t have the pleasure of being near a live band this year, so thankfully we had a Bluetooth speaker nearby to pump tunes from an iPod for us. It kept us jamming for the whole morning.

Race for the Cure is such a fun event. I'm proud of my family that participates with me, and to be a part of the tradition that it has become. They have a great time joining in and being a part of something with my larger Labconco family, all together for a great cause on a great day. We look forward to it every year, and already I cannot wait for next year.

<![CDATA[A well-engineered success story: KU's expansion project]]>http://www.labconco.com/news/ku-expansion-lab Excerpts only: The full original article, "A well-engineered success story" by Jessica Burdg was published in Lab Design News on August 17, 2016. 

The University of Kansas (KU) in Lawrence is a school known for its commitment to students, faculty and the community. Thanks to a recently completed expansion project, the School of Engineering is now better able to fulfill that commitment to its current and future engineering and computing students and faculty. The $105 million dollar project added 185,000 square feet of new construction and renovated existing structures to become a truly well-engineered success story for the university.

Graduating Game Changers

The success of its academic programs has never been an enrollment-only numbers game for KU. Nonetheless, KU Engineering’s goal was to increase the number of engineering graduates by more than 60 percent by 2021.

"You can increase enrollments all you want, but the School of Engineering took a different approach," Professor Robert Parsons, Director of Construction for the Engineering Expansion Project, said. "KU looked at these numbers and said, 'yes, we need to do more.' We want to support our students so they have everything they need to succeed and feel at home here."

That attitude, Parsons said, helps with both recruitment and retention.

Michael S. Branicky, KU's Dean of Engineering since 2013, said he believes the overarching goal of this project was to help graduates continue to go on to be leaders and innovators who affect the state, the country and the world.

"We have KU graduates everywhere from the aerospace industry to the headquarters of Uber. It's this real world notion that you're both learning and learning for a purpose," Branicky said. "For that, we know we need excellent faculty and an excellent facility."

Great lab space by Treanor Architects

Design Delivers New Collaborative Learning Spaces and State of the Art Laboratories

The first phase of the project, the construction of the Measurement, Materials and Sustainable Environment Center (M2SEC), was primarily funded by a grant from the National Institute of Science and Technology (NIST) with a goal of promoting thematically based projects like materials characterization, sustainable building practices and alternative fuels research. Today, the building is a hotbed for innovation, including two "living walls" that monitor environmental change and a space to grow algae on the roof so that it can be compressed and refined to produce biofuels.

. . . .

Completed in Fall 2015, another critical component to the engineering expansion was the construction of the Learned Hall Engineering Expansion Phase 2 (LEEP2) building, which was built as a literal and figurative bridge between the existing engineering facility and the newly constructed M2SEC building.

LEEP2 boasts six active learning classrooms that hold 60 to 160 students. In these innovative spaces, students are engaged in small groups or complete collaborative work more often, thanks in part to a commitment to eliminate tiered or sloped floor classrooms like those often seen in traditional lecture halls...  

. . . .

Besides classrooms, LEEP2 has a number of teaching laboratories—over 11,500 square feet of them, to be exact—including spaces specialized for instrumentation, environmental engineering, building thermal science and more. Nearly 17,000 square feet is dedicated to research laboratories, such as those for analytical chemistry and bioengineering. LEEP2's laboratories feature a variety of state of the art laboratory equipment, including 34 Protector XStream High Efficiency Fume Hoods.

. . . .

Technology at work at KU Expansion Lab

Overcoming Challenges

Like any laboratory design or construction project, the KU Engineering Expansion did not come without its unique set of challenges. For instance, LEEP2 is sandwiched between three existing buildings—including the recently completed M2SEC. A key challenge of the design team was to join all these spaces to produce a cohesive environment that had adequate natural light.

. . . .

A Sustainable, Welcoming Space

LEEP2 adds something else already prevalent among the many buildings across KU's campus: efficiency. The university mandates that their facilities exceed ASHRAE 90.1, and this project did by a minimum of 30 percent. To satisfy this goal, LEEP2 employs the use of heat recovery chillers, energy recovery systems, low VOC adhesives and paints, and a rainwater collection system that pipes fresh water into restrooms.

. . . .

"Prospective students and faculty come in and they see the facilities, the research labs that are very hood-intensive but also very reconfigurable, and they want to stay here," Dean Branicky said. "We've been able to recruit people specifically because of the quality of the laboratory space."

<![CDATA[Freeze dryer accessories make life (and lyo!) easier]]>http://www.labconco.com/news/freeze-dryer-accessories-make-lyo-easier Freeze drying, or lyophilization, is a time consuming process that can be easy or difficult depending on the sample type, sample size and requirements. Using accessories designed for specific samples and challenging applications helps make lyophilizing these samples easier.

Accessories for Stoppering Under Vacuum

When samples are stoppered under vacuum, their shelf life is increased dramatically. Placing airtight seals on the vials before they are exposed to the atmosphere where they can absorb moisture keeps the samples drier. Stoppering under vacuum is determined by your quantity and budget. There are three choices, and deciding which to use depends on the size and number of samples you have.

The first option is a stoppering tray dryer. Although they require a substantial investment, stoppering tray dryers can handle large quantities of samples and offer sophisticated programming capabilities. The FreeZone® Stoppering Tray Dryer has three temperature-controlled shelves (-40° C to +40° C) with 588 square inches of area on which to place samples, which can hold up to four hundred 2 ml serum bottles.

The second option, less expensive than the first, is a stoppering chamber or shelf, which connects to the collector like a drying chamber. Essentially, it is a clear chamber with two heated shelves (+40° C) that provide 158 square inches of area. The Clear Stoppering Chamber has a handle that, when turned, applies pressure to the shelves, collapsing them onto one another and pushing the stoppers into the vials. It holds fewer samples than the FreeZone Stoppering Tray Dryer and uses a more manual process, but the Clear Stoppering Chamber makes sense if your stoppering needs are infrequent or on a smaller scale.

The smallest and most economical accessory for stoppering under vacuum is the Mini Stoppering Chamber. This small chamber connects directly to the valve of a drying chamber or manifold like a flask. It has an area of approximately 18 square inches and is ideal for very small sample sizes or just a few samples that need to be stoppered. It accommodates small bottles and has a capacity of up to forty-eight 2 milliliter bottles or eight 30 milliliter serum bottles. Paired with an isolation valve and a clean bench, the Mini Stoppering Chamber can make stoppering under vacuum in a sterile environment easy.

Accessories to Prevent Sample Melt Back

Unfortunately, sample melt back occurs frequently with several common sample types. The best way to prevent sample melt back is to limit the heat transferring into the sample. This is difficult when freeze drying in a flask, as the heat input is essentially the room temperature that cannot be easily regulated.

Labconco offers Flask Holders that insulate a sample by holding a sample flask inside a larger flask. This creates an even air gap around the sample flask and slows the heat transfer from the room air to the sample.

Alternate options to avoid sample melt back are to insulate the sample container with other materials. A flask can be wrapped with any sort of insulating material, such as packing foam, to create a barrier between the sample and room atmosphere. For samples in a tube, simply place the tube in a flask, fill the flask with water and freeze the entire flask. This creates an insulation of ice all the way around your sample that will lyophilize with your sample.

Freeze Dryer Attachments for Ampules

An Ampule Pod for use with FreeZone Freeze DryersAmpules are glass tubes that are made for very small samples that will be heat sealed under vacuum. Traditionally, ampules are used for long-term storage making it critical they are sealed under vacuum. Due to their size, special accommodations must be taken when connecting them to the collector and it is difficult to lyophilize large numbers of samples at the same time.  

An Ampule Valve Adapter allows a single ampule to be connected directly to a single valve. The Three Way Adapter allows three ampules to be connected to a single valve.

A new option is an Ampule Pod (pictured at right), which connects to a valve and has separate tubes that hold ampules allowing 15 ampules to be freeze dried at once!

Microplates in Freeze Dryers

Samples in microplates can be difficult to freeze dry. Because of their very small size (<1 ml), they are prone to melt back during transfer from the freezer to the freeze dryer and when establishing deep vacuum levels.

Labconco’s new Microwell Plate Holder can help! The molded aluminum block provides a solid mass for better temperature regulation and conduction. The design eliminates the air gap between the bottom of the plate and the freeze dryer’s shelves ensuring good heat conduction throughout the run and reducing the run time. By pre-freezing the entire block, there is more mass around the samples, which insulates and keeps them frozen until reaching deep vacuum.

Accessories for Pre-freezing Flasks

Freezing a sample in a flask at an angle has several advantages over freezing a sample in an upright flask (stub freezing).

The Slant Freeze Flask Holder keeps liquid samples at an angle when pre-freezing. Because liquid expands when freezing, the angled sample puts less pressure on the flask than stub freezing to help prevent the glass from breaking. It also allows for faster freeze drying by increasing the surface area and putting more of the sample in contact with the glass for better heat transfer.

Each freeze drying sample type presents unique challenges, but the right accessories can make the job easier. Labconco is here to help you find solutions to your freeze drying dilemmas.

<![CDATA[Laminar flow in the laboratory: What you need to know]]>http://www.labconco.com/news/laminar-flow-in-the-laboratory What is laminar flow?

Laminar flow in the Type C1 in A-Mode and B-Mode

Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction.

According to the CDC, the laminar flow principle was first developed in the early 1960s. It's still incredibly relevant for modern labs, having literally shaped the way air safely moves in many generations of laboratory enclosures. Today, many categories of laminar flow hoods exist. Although they differ depending on the science performed within, there is one common denominator: all use this type of unidirectional airflow to aid in maintaining sterility, preventing cross-contamination and reducing turbulence.

Just what exactly is laminar flow, why is it effective and what does it look like in labs today? Let's explore.

How is laminar flow utilized in different types of equipment?

Class II Biosafety Cabinets, sometimes referred to as laminar flow hoods, maintain product protection through HEPA-filtered laminar downflow over the work zone. Per the NSF definition, these ventilated cabinets also feature inward airflow at the open front to protect operators and HEPA filtered exhaust air for environmental protection. 

Class II, Type A cabinets recirculate air back into the laboratory unless a canopy connection is warranted. Class II, Type B cabinets are hard-ducted to the outside. Class II, Type C1 cabinets can function in either Type A or Type B mode. Whichever model suits your application, safe operation within biological safety cabinets is imperative to protect the integrity of your work and your personal safety.

PCR stations, enclosures that are specifically designed to house polymerase chain reaction experiment, utilize the vertical laminar flow of HEPA-filtered air to maintain a particulate-free work environment. A UV light is necessary to denature genetic material (DNA, RNA, etc.) and provide secondary decontamination.

Clean benches are suitable for applications that require product protection, such as media plate preparation or tissue culture maintenance. Air is drawn in through a prefilter located at the top of the clean bench before being pulled through a HEPA filter.

In a vertical clean bench, laminar air is then projected vertically over the work area. In a horizontal clean bench, laminar air is projected horizontally towards the operator. In both instances, laminar flow provides a particulate-free work area.

(Note that some categories of laboratory equipment, like Class I enclosures with perforated baffles or certain high performance fume hoods, employ laminar-like flow. Watch: Airflow in a Class I Enclosure.)

So, what is zoned airflow?

Zoned airflow is not truly laminar. Zoned airflow is used when equipment cannot achieve all of the protection required of a Class II biosafety cabinet with standard laminar airflow. Each zone, or column, of airflow is defined and has its own range in airspeed. This allows for higher speed barrier air columns to be utilized as an engineering solution to equipment that otherwise would have poor containment or product protection ratings.

How does laminar flow differ from dilution flow?

Dilution flow is not the same as laminar flow. The dilution flow principle is used in equipment such as filtered glove boxes. In these instances, HEPA-filtered air mixes with and dilutes interior airborne contaminants inside the glove box, and those contaminants are removed via a filtered exhaust system. After the contamination source has been sealed, the dilution rate—or air changes per minute—will determine how much time must lapse before materials can be removed from the main chamber.

What is turbulent flow?

While laminar flow helps to reduce turbulence, turbulent flow encourages it by creating unintentional swirls of air that place particles randomly on surfaces within an enclosure. Turbulent flow can be disruptive to work that requires a dust-free environment and can lead to contamination. Obstructions, like items left inside enclosures, can create this unwanted turbulence.

<![CDATA[Press Release: Axiom biosafety cabinet honored as a finalist for R&D 100 Awards for Innovation]]>http://www.labconco.com/news/press-release-axiom-biosafety-cabinet-honored-as P R E S S     R E L E A S E

For release: August 31, 2016

"Never innovate to compete, innovate to change the rules of the game." -David O. Adeife

Kansas City, MO--Since its release in June 2015, the Purifier® Axiom® —a Class II, Type C1 biological safety cabinet that can function in either Type A or Type B mode—has made waves in laboratory spaces across the country (like this one at Creighton University).  Now, this Type C1 cabinet has been named as one of 100 finalists for the 2016 R&D Awards, an annual event that honors the most innovative technologies of the year.

The list of finalists for what is sometimes called the "Oscars of Innovation" is compiled by over 50 independent judges, many hailing from leading national laboratories and top R&D companies. The selection process is stringent, and the list of finalists includes heavy hitters such as Dow Oil, Gas and Mining, General Motors Research and Development Center, Agilent Technologies and many more.

The Axiom was recognized in the Mechanical Devices/Materials category. The full list of categories for the 54th annual R&D 100 Awards includes Software/Services, IT/Electrical and Green Tech, and many others. Winners in all categories will be announced at a gala to be held November 3 in Washington D.C.

Why the Axiom?

Until now, microbiological laboratories have had to choose between Class II, Type A2 or Class II, Type B2 biosafety cabinets to meet their personnel, product and environmental protection needs. While application and protection considerations have not changed, something else has—the options for selecting a cabinet. Because the Axiom is an entirely new type of Class II biosafety cabinet, it can function in either Type A or Type B mode, saving money, time and energy in the process.

Wondering what makes it work? It has a lot to do with airflow—and a lot do with the perseverance of the team of user-first designers and engineers at Labconco.

Senior Products Engineer Jim Hunter and Product Manager Brian Garrett, two of the brains behind what's been appropriately dubbed the BSC no-brainer, have spoken in the past about the challenges of developing an entirely new type of biosafety cabinet. Since R&D's list of finalists was released in August of 2016, though, they've had to prepare an altogether new type of statement: one of acknowledgement of their team's success.

"The Axiom challenges many of the preconceptions of what a biosafety cabinet should be; it is far more flexible in its installation, either connected to an exhaust system or not," Hunter said. "And, for the first time, the BSC takes an active role in protecting the user, even in the event of an exhaust system failure."

Garrett added that the goal of the project was to add flexibility to laboratory spaces while increasing safety in the industry for scientists doing all kinds of important work in the field.

"It's an incredibly big deal to be going up against the gorillas of innovation and invention in our space, and we're proud of what our team was able to accomplish," he said.

<![CDATA[Cart for the Cure: Keep on rolling!]]>http://www.labconco.com/news/keep-on-rolling Promotions are always great, but when they support a charitable cause, they’re all the better! Each fall Labconco does just that with Cart for the Cure™. This will be our sixth year running this promotion and we couldn’t be happier.

To create the Cart, we chose the official Breast Cancer Awareness pink to paint our Labconco Portable Table. In our Fort Scott, KS facility where these carts are manufactured, the entire paint line from the booth to the hoses to the air handling system is emptied and cleaned before being filled with the pink paint. Each Cart for the Cure’s 18-gauge welded tubular steel frame then receives its glowing, pink coat. The paint line’s whole draining and cleaning process is repeated when the pink is removed. Because of this, the carts are produced in large batches to limit the number of times the paint colors must be changed. Luckily, our new paint system drastically reduces the time required for the process.

I want my Pink Cart for the Cure

 
A large batch of pink "Carts for the Cure" on the Labconco Fort Scott, KS paint line

The cart includes all of the features of our Portable Table – sturdy steel construction, two open shelves, ergonomic molded plastic handle grips and a lifetime guarantee. Each shelf runs the full length and width of the cart for more than 625 square inches of storage space per shelf! The final touch is a pink ribbon identification tag to hang from the frame to ensure everyone knows the meaning behind the cart.

How it works: Donations and savings

Labconco donates $50 for each cart purchased to the Saint Luke’s Foundation. When we began this journey, the donation went to the Spelman Medical Foundation, so when Spelman merged with the Saint Luke’s Foundation on January 1, 2013, we continued our commitment. These organizations do great work to provide health information and services to uninsured and underinsured women as well as seniors. They are particularly focused on breast and ovarian cancer and provide mammograms to women who cannot afford them.

Furthermore, for three months during the fall, usually September through November, Labconco offers an extra incentive. To bring more awareness to breast cancer from the month before until the month after the national (U.S.) Breast Cancer Awareness Month (October), the cart’s list price is lowered by $100. The $50 donation continues year-round. Many of our dealers participate and share the promotion as well, allowing us to see continued growth in the popularity of this wonderful promotion.

Within Labconco, we have a Pink Cart Team to promote Cart for the Cure and manage internal fundraisers including food sales and raffles during the months of the promotion. We also participate in the Race for the Cure put on by Susan G. Komen of Greater Kansas City. At the end of each year, Labconco presents the full donation to the Saint Luke’s Foundation.

<![CDATA[Lyophilization, evaporation or concentration: Which is best for my samples?]]>http://www.labconco.com/news/lyophilization-concentration-or-evaporation-whic Lyophilization, vacuum evaporation and nitrogen blow-down evaporation are all methods to reduce sample volume; however, each method involves a different process and affects samples differently. It is important to identify which evaporation method is most appropriate for your sample in order to identify the right specific equipment to use.

Lyophilization, evaporation and concentration cause liquid or solid molecules to undergo phase changes, resulting in aqueous or solvent molecules leaving the sample as a vapor. The main force that drives the phase change is heat energy. The best evaporation method for a sample is mainly determined by how much heat the sample can withstand.

Forces that Catalyze Evaporation

If a sample is not affected by heat, simply place the sample on a hot plate and let it boil until the sample volume is reduced to the desired level. Unfortunately, most samples are affected by heat, with biological samples being the most sensitive. In heat sensitive samples, the amount of heat driving the phase change must be limited or the sample will be damaged. When heat is limited, other forces must be used to drive molecules through the phase change instead.

Applying a vacuum atmosphere is a common technique used to force molecules through the phase change during evaporation or lyophilization. Boiling points of liquids are greatly reduced under vacuum, so phase changes occur at lower temperatures and less heat input is required. As a result, vacuum concentration or lyophilization are the most optimal methods for biological or heat sensitive samples.

Another technique that expedites the phase change of solvents is introducing a nitrogen stream at the surface of samples. The nitrogen stream disrupts the balance between the liquid and vapor phase and encourages the molecules to move into the vaporous phase. As a general rule, nitrogen blow down evaporation requires a higher heat input than vacuum evaporation. Because of this, nitrogen blow down evaporation is commonly used for volatile solvents or samples that are not damaged at moderate temperatures.

Lyophilization (Also Know as Freeze Drying)

Lyophilizers use deep vacuum (< .200 mbar) and heat to remove moisture from a sample. The drying process, or phase change, in lyophilization is unique and is called sublimation. In sublimation, molecules go directly from the solid phase (ice) to a gaseous phase (vapor) without passing through the liquid phase.  Lyophilization requires a frozen sample.  If the sample’s freezing point is suppressed by the presence of solvents, the solvents should be removed with vacuum concentration prior to lyophilization so that the sample can then be frozen solid.

By circumventing the liquid phase in sublimation, the biological viability of many samples is preserved. This makes lyophilization a unique type of evaporation as it also preserves biological samples.

View Lyophilizers

Vacuum Concentration/Evaporation

In vacuum concentration/evaporation, the sample is dried by converting liquid to vapor. Vacuum concentrators and evaporators take the liquid sample to 99% dryness in a relatively short amount of time and can accommodate most samples regardless of their freezing or boiling point.

Vacuum concentrators and evaporators are commonly used in sample preparation, and use centrifugal force, heat and vacuum to remove moisture from a sample. What makes concentrators different from evaporators is how the centrifugal force is generated and how the heat is supplied to the sample.

In a vacuum concentrator, samples are held in a rotor that spins at 1700 RPM creating a centrifugal force.  The centrifugal force prevents liquids from bumping out of the tube when vacuum is applied. Heat is applied indirectly through the walls of the vacuum chamber.

A vortex evaporator uses centrifugal force, heat and vacuum to remove moisture from a sample. Unlike the spinning motion of a vacuum concentrator, the vortex evaporator creates a vortex motion within the sample container so that centrifugal force holds the sample into its container while vacuum is applied to the liquid sample. Without an opposing force to hold the sample into its container, it would “bump,” or splatter out of its container. Vortex motion, washes the analyte (analyzed material) down the sidewalls of the glassware, increasing the recovery of the analytes being tested. In vortex evaporation, heat is applied directly into a sample through a block that holds the sample.

View Vacuum Concentrators

Nitrogen Blow-Down Evaporation

Nitrogen blow-down evaporators use heat and a nitrogen stream to evaporate moisture from a sample. Evaporation rates can be increased if a vortex motion is created to increase the surface area of the sample. Dry block heaters are commonly used in these evaporators and offer many advantages over water baths.

<![CDATA[How many trees are there in a grove?]]>http://www.labconco.com/news/how-many-trees-are-there-in-a-grove A single large tree can produce enough clean oxygen to support four people, according to the Arbor Day Foundation. So the answer is simple: There can never be too many.

But what if you planted an entire forest?

With the help of the Arbor Day Foundation, Labconco has planted 725 trees as part of our commitment to our environment and to expanding sustainable building practices. And we aren’t finished yet. For every Protector® Echo™ or Airo™ Filtered Fume Hood your laboratory invests in, Labconco will plant another grove of trees. 

Planting trees is our way of doubling the positive environmental impact that your laboratory makes when you put a filtered hood where a traditional hood may have otherwise gone. Much like a tree converting CO2 into oxygen, filtered fume hoods turn chemically contaminated air into clean, life-sustaining air.

Other environmental benefits

For some laboratory applications, filtered hoods are the best way to save energy as well. Since standard fume hoods pump your heated or air-conditioned air out of the building, they’re often the largest energy drain (and the largest utility expense) for organizations that support a scientific lab. That’s another way filtered fume hoods help your lab leave a much smaller carbon footprint while lowering energy bills.

A fume hood expert can tell you how a filtered fume hood would affect your laboratory, your environment and your budget.

<![CDATA[The good, the bad and the ugly of UV light usage in a Class II BSC]]>http://www.labconco.com/news/2-uv-lamp-rules For decades, germicidal UV lamps have been used in Class II Biological Safety Cabinets. The purpose is to keep a biosafety cabinet’s interior clean when not in use. Many researchers swear by the use of their UV lamp and would never consider owning or buying an enclosure without one. Others believe UV lamps provide a false sense of security or don’t see the merit in a UV lamp (such as the NIH). Germicidal lamps utilize UVc radiation (typically at 254 nm wavelength). This energy is very good at doing a specific task, but it’s a poor broad spectrum decontaminant, and here is why:

The Good:UVc is a recommended accessory for your BSC or laminar flow bench when working with cell cultures, PCR or other genetic materials because UVc radiation is efficient at breaking up chemical bonds and denaturing DNA and RNA. Under prolonged exposure, these chemical changes lead to dysfunctional genetic material and eventual cell death.

The Bad: Germicidal lamps use low energy radiation—so low that the waves are incapable of penetrating barriers or of reflecting from most surfaces. This simply means that for UV lamps to be effective, the target MUST be in direct line of sight with the light source. This is bad if you are using a germicidal lamp as the primary decontaminant in your lab’s culture enclosure. However, for those folks populating the lab or standing outside of the enclosure with nothing but a sheet of glass between them and the blue tube of light, this is a good thing. It means that sheet of glass is more than sufficient to block you from becoming irradiated.

The Ugly: Use of a UV lamp for the purpose of primary decontamination is rampant, as is the frequency of cross contamination. True, cross contamination can be caused by a number of factors – but experience shows that labs utilizing UV lamps as the only means of “cleaning” their BSC have a higher prevalence of such issues.

Two simple rules for using UV lamps

1.     If you are using “naked” DNA / RNA or performing PCR... UV lamps are excellent at rendering these materials harmless.

2.     If you are doing anything else with biological material… do not rely on UV lamps alone to keep your work area clean. ALWAYS wipe down exposed surfaces with a proper decontaminant PRIOR to turning on the UV lamp. ALWAYS wipe down exposed surfaces with a proper decontamination AFTER turning off the UV lamp.

 

Learn about the new Type C1 biosafety cabinet. It does the work of an A2 and a B2 at a lower cost of ownership.

<![CDATA[4 things to consider before choosing a ductless fume hood]]>http://www.labconco.com/news/considering-a-ductless-hood Ductless fume hoods, sometimes called carbon-filtered enclosures or filtered fume hoods, are self-contained, filtered laboratory enclosures that remove hazardous fumes, vapors and particles from the laboratory. Unlike traditional fume hoods, installation costs are very low and no ductwork is required. Therefore, many people think selecting one is a slam-dunk when they first learn of them.

“It takes care of the chemical fumes, it’s cheaper, and it’s an easier installation. It only makes sense, right?”

Not. So. Fast.

There are some important things to consider before making the final decision to purchase a ductless fume hood. Take these four aspects into thorough consideration to be confident that a ductless fume hood is the right choice for your laboratory and your applications:

1. Is your general application appropriate for a ductless fume hood?

Although there are different classes of ductless and filtered fume hoods, some hoods still limit applications that can be performed in them. Some ductless fume hoods should only be used light-duty or process-specific fume hoods. Other filtered fume hoods can be used for a wide range of chemicals, but keep in mind that larger chemical volumes will always shorten filter life. 

This means that:

  • A limited number of different chemicals should be used.
  • No extreme heating should be carried out in the hood, i.e. acid digestion applications.
  • Modest chemical volumes should be used, around 500 mls or less per chemical.
  • Moderate chemical exposure times should be maintained.

If your application does not meet these parameters, a standard ducted fume hood is likely the best option for maximum safety and economical feasibility. If you do not know what chemicals will be used in the future, or you have a very long list of chemicals, the application would best be performed in a ducted fume hood.

At this point you should discuss your application with a Fume Hood Specialist to confirm which kind of fume hood is primarily recommended.

2. Will the chemicals involved in your application be effectively filtered with the available carbon filters?

Typically, ductless hoods will be outfitted with chemical specific filters. Specific filter types increase chemical trapping capacity for different chemical families; however, some chemicals cannot be safely filtered or aren’t filtered effectively enough to allow ductless hoods to be a financially viable option. Filtered fume hoods can filter out acids, bases, and solvents with one filter type, however, there are still some chemicals (low molecular weight solvents) that will not be effectively filtered. 

To filter various chemical groups, Labconco offers seven different types of carbon filters for use in our ductless fume hoods:

  • HEPA (High Efficiency Particulate Air) Filter: a 99.99% efficient particulate filter for chemical powders and particulates
  • Organic Carbon Filter: Activated carbon to chemically adsorb organic vapors
  • Acid-Sulfur Carbon Filter: Impregnated carbon to neutralize Acids and Sulfur containing compounds
  • Ammonia-Amine Carbon Filter: Impregnated carbon to neutralize ammonia/amine compounds
  • Formaldehyde Carbon Filter: Impregnated carbon to neutralize formaldehyde
  • Mixed Bed Carbon Filter: 60 % Impregnated carbon to neutralize acids and sulfur containing compounds (20%), Ammonia and amine compounds (20%), formaldehyde containing compounds (20%) and 40% activated carbon for organics
  • Radioisotope Carbon Filter: Impregnated carbon to neutralize radioisotopes
  • Neutrodine® Carbon Filters: a comprehensive filter type for use in our Echo and Airo Filtered fume hoods.

If all of the chemicals involved in your application match one of these filter types, it is a good sign that your application will be suitable for use with a ductless fume hood; however, there are some chemical exceptions with each filter type. For instance, some organics (such as methanol) are very volatile, light weight, and are not effectively adsorbed on the organic filter.  Whereas some acids (like perchloric acid) present special hazards and should be used in a specialized fume hood.

The best way to determine if your chemicals are compatible with the filter types offered is to request a Chemical Assessment from our Chemical Specialists. They will review your application to help you determine if it is suitable, make appropriate equipment and filter recommendations, and provide you with any necessary precautions.

In some cases, you may be able to determine the correct filter type using our Chemical Guide for Ductless Hoods. Remember, though, the Guide is not an approved list of chemicals; you and your safety officer must ultimately determine which chemicals, quantities and filters ensure your personal safety.

3. How often will you have to replace your filters?

Although you will not have the added cost of ductwork installation and wiring associated with a standard fume hood, you will still want to consider how often you would need to replace your filters, and the maintenance costs associated with that, to calculate your estimated annual filter costs. Filter lifespans can last from a few months up to two years. You will want to find out how long the expected filter lifespan is for your application, then weigh that against the cost to install a standard fume hood. Also consider the energy cost of running a standard fume hood, which removes tempered air from the laboratory, taxing the HVAC system.

Filter life (and filter replacement times) depend on several factors:

  • What chemicals are being used?
  • What is the filter capacity for the chemicals being used?
  • What is the evaporation rate of each chemical?
  • What is the chemical volume that is being used?
  • What is the duration of usage per day for each chemical?
  • What is the temperature of each chemical?

<![CDATA[How long will it take to freeze dry my samples?]]>http://www.labconco.com/news/how-long-will-it-take-to-freeze-dry-my-samples

People in the lab often contact us with the seemingly germane question, “How long will it take to freeze dry my samples?” We wish we could give a definitive answer to this question, however the answer we have to give is: It depends. Given the numerous potential applications and conditions, the length of the freeze dry process will vary.

The majority of laboratory samples will lyophilize in 24 to 48 hours but there are certainly exceptions.

The freeze drying process is dependent on a variety of factors that determine the amount of time the freeze drying process requires.

Sample type

The freezing temperature (eutectic point) of the sample and the presence of salts, sugars, or solvents will influence the length of time required to lyophilize successfully. A low freezing point sample or one that is susceptible to melt back, will require a longer lyophilization cycle.

Sample size

The more volume to lyophilize, the longer the freeze dry run.

Flask size

Spreading a sample out over a greater surface area allows more contact for heat input and shortens the distance in which the drying front has to move through the sample. As a general rule, freeze dry flasks should be filled to only one-third of their total volume.

How the sample was frozen

Faster pre-freezing rates, result in the formation of small ice crystals. Small ice crystals generally require longer freeze drying runs. When samples have small ice crystals, the cake that is formed in subl

imation, is less porous and harder for water molecules to move through. This slows the sublimation rate.

Freeze dry system

It is important to select the correct freeze dryer for the sample. The freeze dryer’s collector should be 15°C-20°C colder than the sample’s freezing point. The instantaneous load capacity and the collector capacity should be able to accommodate the sample volume. If either one of these parameters are undersized, the rate of sublimation will be affected.

Amount of heat and how heat is transferred to the sample

Energy in the form of heat is what is driving the lyophilization process. The more heat that the sample gets, the faster the run.

Because freeze drying is such a popular laboratory method, there are thousands of methods published on a wide variety of sample types. Before you begin, search online for published methods for your type of sample or as close to your sample type as you can find. Use the published parameters as a starting point.

When developing a lyophilization protocol the first objective should be to first; freeze dry successfully, then optimize the run time.  We recommend beginning your method development with non-valuable samples that are similar to your real sample, as it may take several trials to get the parameters correct.

Once a working protocol is established that produces consistent results, then freeze dry the more valuable samples. After you have established a method that is producing good results, the next step is to tweak the parameters to reduce the run time.

To learn more about optimizing lyophilization parameters, read the article, How to Freeze Dry Faster.

Now here are some examples of applications and their typical run times from FreeZone customers.

<![CDATA[4 Reasons You Should Use a Remote Blower Instead of a Built-In Blower]]>http://www.labconco.com/news/4-reasons-you-should-use-a-remote-blower-instead Fume Hood Blowers: An Exhausting Subject

A blower, or exhaust fan, is a very important part of a fume hood system. It is the component that moves air through the fume hood. Many people are under the impression that all fume hoods come with a built-in (or integral) blower.

A built-in blower is mounted right above the fume hood. In that scenario, the blower pushes the contaminated air out from the hood, through the ductwork, to the outside.

In most labs, however, a remote blower is used, as shown in the Typical Fume Removal System graphic to the right. This means the blower is located remotely from the fume hood, on the rooftop typically, and pulls the air all the way through the duct work to be exhausted outside. 

There are many things to consider when choosing a blower. Here are four reasons why you should always use a remote blower over an integral blower.

1. Fume hoods with built-in blowers to duct outside do not meet ANSI Z9.5!

If your specification requires compliance with ANSI Z9.5, you must use a remote blower. Section 5.4.4 of ANSI/AIHA Z9.5-2012 clearly states:

Laboratory exhaust fans shall be located as follows:

  • Physically outside the laboratory building and preferably on the highest-level roof of the building served. This is the preferred location since it generally minimizes risk of personnel coming into contact with the exhaust airflow.
     
  • In a roof penthouse or a mechanical equipment room on the roof that is always maintained at a negative static pressure with respect to the rest of the facility, and provides direct fan discharge into the exhaust stack(s).

So if your blower is mounted on top of your fume hood, it won’t be “physically outside of the laboratory building” and it won’t be located in a “mechanical equipment room that is always maintained at a negative static pressure with respect to the rest of the facility.”

2. Remote blowers are safer

A remote blower is a failsafe, meaning if there is a leak in the duct work at any point, the duct is kept under negative pressure. In the event of a leak, clean air will be pulled through that leak and exhausted out, instead of pushing contaminated air out of that leak (as a built-in blower would).

If you have an application with hazardous chemicals or a building where your fume hood duct run goes through multiple occupied floors, a remote blower should be used.

3. Built-in blowers are not a one-size-fits-all

Every blower has a blower curve chart that shows under what circumstances the blower can operate properly. This includes the static pressure and CFM requirements (shown in the figure to the left).

The mechanical system has to fit the integral blower. So even though you have a duct run that is only 10 feet long, that does not mean it will work well.

It will most likely require a manual control damper to add resistance to the line. Blowers require a certain amount of resistance, or static pressure, to work effectively.

Think of it like using a blender to make a smoothie, if the ice doesn’t fall to the blades, the motor goes too fast and you can sometimes smell the motor burning up since it does not have any resistance to work against. It’s the same concept for a blower motor – it requires resistance to work properly.

4. Built-in blowers are louder

Noise issues can arise for a couple different reasons, but there is no doubt, when the blower is sitting right on top of the fume hood, it will be louder than if it were mounted on the rooftop. If there is noise sensitivity, for example in a classroom setting, it’s highly recommended to have a remote blower so the teacher doesn’t have to speak over the blower motor while teaching.

The air turbulence itself can create noise as well.

Things that contribute to the air noise are the duct material (metal is loudest), and the duct run design (the more bends, the louder). So it is always recommended to put 3 to 5 duct diameters of straight duct before and after each bend, and off the fume hood exhaust collar, in order to straighten the air colun and reduce the turbulence. 

Those are the four reasons a remote blower should be used over a built-in blower. Obviously there are scenarios where a built-in blower must be used, but one should always consider a remote blower first, then move from there.

I would only recommend using a built-in blower if you absolutely cannot use a remote blower.

And now here's a helpful graphic explaining positive (+) and negative (-) pressure as it relates to blower location and safety. Enjoy.

<![CDATA[Water World – Quenching Your Thirst For Purified Water]]>http://www.labconco.com/news/water-world-quenching-your-thirst-for-purified Trying to find a laboratory without purified water is like trying to find someone who enjoyed the movie "Waterworld." It’s... Well… It’s challenging. From solutions and dilutions to washing, water is widely used in science.

So it’s only a matter of time before you will have to decide on a water purification system for your laboratory.

Fortunately, determining the best type of water purification system for your lab won’t require a journey into "The Abyss." Just take a look at these common laboratory experiments and their recommended water purity grades to find a match for your application.

General Water

Does your lab need to feed Type I water systems, rinse glassware with purified water, or feed glassware washers and autoclaves? If you answered yes, then your lab needs Type III water, also known as Reverse Osmosis (RO) water. Type III water is the most widespread type of laboratory water and has 90 to 99% of contaminants removed via an RO filter.

Labconco’s WaterPro RO System for Type III water features a production rate of 1 L/min and storage for 17L of purified water for painless integration with glassware washers and Type I water systems.

Analytical Water

Do you perform HPLC, GC, ICP-MS, Atomic Adsorption, In-Vitro Fertilization (IVF), Cell/Tissue Culture or Buffer Preparations? If so, then Type I water, the purest form of laboratory water, is recommended. Type I water, which is achieved by polishing RO water through carbon and deionization filters, is also known as Ultrapure or 18 Megohm water.

Labconco’s WaterPro PS Systems for Type I water come in easy-to-understand configurations tailored to the most specific needs of any chemist or biologist. With options for UV reactors, trace organic filters, plus ultrafilters and a production rate of up to 1.8L/min, Labconco WaterPro PS Systems deliver ultrapure water for any task.

Need both Type I and III water? Pair up the WaterPro RO and PS systems for high output. Try the cost-effective WaterPro BT, a space-saving benchtop model, for laboratories that require < 10 liters of purified Type I and III water.

Now that you’re out of "Open Water" and into the "Blue Lagoon" of water purification, you’re ready to lead your lab from the dry land of "Mad Max" by diving "20,000 Leagues Under The Sea." You can groan now!

Have an application or water type that wasn’t covered? Labconco is just a phone call away at 800-821-5525.

As a bonus, below we have a valuable graphic on water types to "wet" your appetite.

<![CDATA[Flexible equipment optimizes modular lab design]]>http://www.labconco.com/news/flexible-equipment-optimizes-modular-lab-design Modularity is a recurring request in new lab designs. With the laboratory’s technology needs and space requirements constantly changing, modular design offers the capacity to change a specific laboratory's function simply by moving a few things around or repurposing existing equipment.

Modular design makes it easy to bring in new equipment or remove unwanted equipment without the hassle of a complete redesign, demolition and the associated costs.

However, modularity could cause issues for the tried-and-true workhorses of the standard laboratory. Example: The chemical fume hood, a necessity in almost every lab.

Traditional chemical fume hoods are designed to evacuate noxious or hazardous chemical vapors from the building by physically ducting them through the structure and out of a roof-mounted blower . Unfortunately, in the process of evacuating fumes, a large amount of conditioned (heated or cooled) lab air goes along for the ride. The process is hardly cost effective or green – it is estimated that exhausted air costs $7 to $8 per CFM per year.

In an effort to address issues like this, there are many laboratory equipment products that provide modularity through flexibility.

Hazardous Chemical Applications

Ductless fume hoods and enclosures are self-contained and use carbon filtration to efficiently adsorb chemical fumes and vapors. Air that has been scrubbed of these contaminants is then returned to the laboratory. Since the tempered air (heated, cooled, and/or dehumidified) never leaves the building, great energy and budgetary savings are gained. By avoiding ducting to the outside, ductless hoods offer the flexibility of making traditionally stationary units mobile. Furthermore, the wide array of filter types for some ductless hoods and the robust chemical containment and filtration of filtered fume hoods, offer great flexibility for changing hazardous chemical practices.

Ductless hoods come in three different configurations. Ductless Hoods Tier 1 (DH I) are used for nonhazardous chemistry. These are great for staining operations or handling chemicals that are not hazardous but may be a nuisance or cause sensitization. Ductless Hoods Tier II & III (DH II & DH III) can both be used with chemicals and with specific operations the hood manufacturer approves.

Hazardous Compounds & Particles (non-biological)

Handling hazardous chemicals and their associated vapors through mass airflow typically follows the age-old rule that “the solution to pollution is dilution.” Fortunately, filtration can be used to “green” this philosophy. However, unlike work that produces chemical fumes, work with potent chemical powders, environmental soils, asbestos and similar materials cannot be addressed through mass airflow or carbon filtration. Rather, it requires particulate filters, often in the form of High Efficiency Particulate Air (HEPA) filters.

Self-contained HEPA filtered enclosures provide user protection while handling, opening or processing materials that cannot be controlled through mass airflow and dilution alone. They can often be mounted on existing bench space or on wheeled stands for mobility. Furthermore, these environmental enclosures can be configured with features, suiting them to specific tasks (ie.bag-in/bag-out HEPA filter systems, waste chutes and ULPA filters).

Microbiology & Biohazardous Material

Things you cannot see can indeed cause harm to you, your coworkers, and your laboratory. In this case we are referring to biohazardous aerosols. Often as an effect of simple microbiological processes, gross amounts of aerosolization can occur and is rarely visually noticeable and often is not realized. Such processes are not limited to, but include homogenization, vortexing, pipetting, aspiration, material mixing and transfers, glove removal, using syringes, stirring, and grinding.

These applications call for a specialized hood called a biological safety cabinet (BSC). Evolving from the “laminar flow biohazard hoods” of the 1970’s, these also come in various forms and configurations. A risk assessment will quickly point to which of the variations is required for any given procedure. In brief, Class I BSCs protect the operator and laboratory from the microbiology within. Class II & Class III BSCs protect the operator, laboratory from hazards within and also the process from room contamination. Class III BSCs (biological isolators or glove boxes) provide the maximum level of protection by creating a physical barrier between the work and the operator, but are ungainly to work in.

If chemicals are included with the microbiological work then connecting that BSC to an exhaust system may be required (similar to a chemical fume hood). Flexible BSC designs like the Class II, Type A2 with canopy or the new Class II, Type C1 offer increased flexibility of installation. Only the Type C1 has the flexibility of both installation and containing hazardous biology and chemistry.

Vacuum Networks

The majority of modern laboratories are built with vacuum network lines. However, before tapping into these networks, first determine what kind of work the vacuum will be doing for you and the lab and the potential consequences of using a common vacuum source for your work. Vacuum networks are built into a building’s infrastructure, and once in place offer very little flexibility. Local and lab selected vacuum pumps and systems offer great flexibility and mobility, but come at a cost to the lab’s budget – not the entire building’s budget.

If you perform aspirations on samples containing controlled or infectious materials using a vacuum network, the entire network can become contaminated with hazardous materials. Furthermore, you could cross contaminate the vacuum for the lab next door or on another floor. Consider the cost effectiveness and risk mitigation of using dedicated vacuum systems for such operations.

Also consider the depth of vacuum required for the work. Lyophilization (or freeze drying) requires a considerably deeper vacuum than built-in vacuum networks can provide. Before installing a lyophilizer, concentrator, evaporator or dessicator, know what vacuum levels will be needed and plan accordingly.

Laboratory Water (Deionized, Reverse Osmosis, Polished, etc…)

Finding a lab without a water system is as difficult as finding water on the parched desert planet of Arrakis (nerdy Frank Herbert’s Dune reference). As soon as lab planning commences, water resources should be understood and communicated. While it can be advantageous to have a large “house” water system installed, water purity and volumetric demand concerns will invariably arise.

It typically is more cost effective to keep house-water to a very basic and maintainable level (RO or ‘gross’ DI (down to 20-10 microsiemens)). Getting laboratory water any cleaner than this from a building’s water supply will be wasteful for two reasons:

  1. There will likely never be enough water.
  2. The water quality will suffer as it flows to the end of the line to point of use.

Consider the water quality that is needed at point of use and install wall mounted or small bench top water systems that can further polish water to the level needed. This ensures that only the volume of water needed is actually used, and that when used it is the quality required for the laboratory’s operational needs.

Cleaning Glassware

Like water, discussed above, all labs use glassware to some extent. Many labs clean their glass by hand, because interns and undergraduates are free, right? There are a couple of pitfalls in using this strategy. First, while their time may be free, it can be used in other, more productive endeavors. Secondly, intern A likely does not wash to the same quality as undergraduate B, or principle investigator C. Finally, hand washing wastes water.

Glassware washers put an end to these concerns, and can be made to be flexible (unlike the dishwasher at home. Under-counter washers can be retrofitted with finishing panels/facades, wheels and quick connect fittings; making them mobile and flexible. Mobility addresses space limitations while adding water saving and repeatability of the washer to multiple lab spaces that use relatively little glassware (thus maximizing the lab’s investment).

<![CDATA[Ducted or Ductless? That depends...]]>http://www.labconco.com/news/ducted-or-ductless-that-depends If you’re stuck in a place between a fume hood and a hard ceiling, consider using a filtered fume hood. Since more and more laboratories find they cannot duct out, or are choosing not to duct out in order to save on energy costs, there is a diverse range of carbon filtered fume hoods for most chemical fume hood needs.

A large misconception is that a ductless hood is the same across the board –with this being said, if you are interested in a ductless or filtered fume hood, be sure to have a list of chemicals and applications handy so a chemical assessment can be performed to see what type of enclosure is appropriate.

In my lab days, most fume hoods looked alike—a glass sash that could be raised or lowered, one switch for a light and another to turn air on and off. Today’s fume hood world features many options, including filtered hoods...

<![CDATA[To B2 or Not to B2? Thanks to the new C1, That is No Longer the Question...]]>http://www.labconco.com/news/to-b2-or-not-to-b2-thanks-to-the-new-c1-that-is Regardless of your industry, having the right tools for the job matters. That statement goes both ways, too: Of course you want equipment that allows you to perform effectively and safely, but you don't want to incur any added expenses for features or protections your work doesn't necessarily warrant. 

In other words, if you're a carpenter, you're going to need a hammer—a good, dependable hammer. You don't want to reach for the blunt end of a screwdriver in desperation or have to read an instruction manual for a complicated, expensive gadget you're too frustrated to use.

What if your hammer could do other things you needed it to do, though, and actually save you money in the long term? Well we haven't invented that—we don't sell hammers. Sorry. But we did engineer a completely new biosafety cabinet that can function in either Type A mode or Type B mode, and it's swiftly becoming the Swiss Army Knife of sorts for laboratory toolboxes around the U.S. (like this one at Creighton University).

Before we explore the Purifier® Axiom™ Class II, Type C1 Biosafety Cabinet, though, let's delve into the backstory about why this technology is indeed so novel. It starts by addressing the longtime struggle of many labs in determining what kind of cabinet—a Class II, Type A2 or Class II, Type B2—they actually required.

BSC Choice Struggles of Yore

Although the field of laboratory research is one rooted in change and new discoveries, one thing remains unchanged: Safety matters. (Read what industry expert Sean Kaufman has to say about safety in labs here).

It matters so much, in fact, that we've received many inquiries in the past from customers wanting to purchase Type II, Class B2 total exhaust cabinets with the misconception that these units were safer than their Type II, Class A2 counterparts.

That's only partly true, and it comes with a hefty application caveat. Type B2 cabinets aren't only safer when your microbiological work requires the use of volatile toxic chemicals or radionuclides—they're required.

In other words, if your application includes hazardous chemistry, you must have a hard-ducted Type B2 (or C1, as we'll get to in a moment).

It's important to note here that although they're often used interchangeably in the industry, 'hazardous chemicals' and 'hazardous chemistry' do not mean the same thing. For example, if you're working with a hazardous chemical, you don't necessarily need to opt for a Type B2 cabinet if that chemical is diluted enough to be rendered non-hazardous. Is that clear?

For many, it's understandably not—that's why a risk assessment must be performed to determine if the volume and concentration of the chemistry you're going to perform is indeed hazardous. Remember . . . safety matters.

Some risk assessments will find that the application in question warrants a Type A2 biosafety cabinet, a unit that exhausts about 30 percent of its total airflow while recirculating the remaining 70 percent within the cabinet. In contrast, airflow through a Type B2 cabinet is similar to that of a fume hood, externally exhausting 100 percent of the air pulled through the cabinet. The purpose of this design is to completely remove any toxic chemical vapors or radioactive compounds that are generated inside the cabinet.

Room air is brought into the cabinet through both an opening in the top of the cabinet and through the inlet grille. This air flows through an initial HEPA filter and then downward through the work area. All of the contaminated air is then drawn into a negatively pressured plenum and exhausted through a second HEPA filter. A dedicated exhaust system and remote blower draw all of the filtered exhaust air out of the laboratory.

At the end of the day, Type A2 cabinets and Type B2 cabinets are equally safe when used for the properly designated applications. After all, they both utilize HEPA filtration and protect against agents requiring biosafety level (BSL) 1, 2, or 3 containment. In the past, researchers who needed both Type A and Type B functionality would have been forced to purchase both types of cabinets—that is, until today.

Type C1 Biosafety Cabinet: Best of Both Worlds

As you've probably gathered by now, the Class II, Type C1 biosafety cabinet can convert from operation in Type A mode to operation in Type B mode, the first of its kind. Running the Type C1 in B-mode is cost-effective, too, as it tallies near the operating cost of a traditional Type A2 cabinet with canopy connection. It can be tied to almost any existing exhaust system with sufficient CFM reserve, so installation costs are minimal compared to traditional Type B2-only implementations.

With dual ECM blowers and our very own Constant Airflow Profile™ (CAP) technology, safety comes first on the C1. In fact, the unit maintains safety for both you and your work, even in the event of a building exhaust failure.

Thanks to the design of the Chem-Zone™—the center of the dished work surface that serves as the dedicated exhaust portion of the cabinet when in Type B mode—airflow demand is reduced by more than 50 percent (compared to traditional Type B2 cabinets).

In short, the Type C1 is changing the biosafety game, combining unparalleled versatility, flexibility and safety. Labs like yours no longer have to teeter the line between Type A and Type B or purchase multiple units to satisfy multiple needs because the Type C1 is capable of handling any application. To B2 or not to B2, then, is no longer the question.

<![CDATA[Science Pioneers and Science City Join Forces]]>http://www.labconco.com/news/science-pioneers-and-science-city-join-forces In 1956, Science Pioneers was incorporated in Kansas City as a non-profit organization to foster, develop and encourage youth in the study of science, technology, engineering and mathematics (STEM).

Fast-forward to 1999 and Science City opens its doors as part of the reconstructed Union Station with a similar mission – to interest local and national youth in the sciences.

In 2002, both Science Pioneers and Science City found themselves residing in Union Station. With complementary programs and mission statements, it was only a matter of time before these two would become one. That time has come.

Starting July 1st, Union Station’s Science City and Science Pioneers will merge to complement each other’s strengths and bring STEM to a larger audience than before. This is great news for Kansas City and Labconco Corporation.

Being a part of Kansas City and the global scientific community since 1925, Labconco values our existing relationship with both Science City and Science Pioneers – we were a sponsor of the 65th Annual Greater Kansas City Science & Engineering Fair ­– but now there will be more synergy than ever before. Since its inception, the fair has grown by leaps and bounds.

“We simply can’t imagine a better union between two brands with a common purpose and community-affirmed outcomes,” espouses George Guastello, president and CEO of Union Station Kansas City. Both non-profits sponsor the science fair and are similarly housed inside Union Station in downtown Kansas City.

LeAnn Smith, executive director of Science Pioneers, adds, “For non-profits to grow and flourish it’s essential to collaborate with like-minded organizations. By bringing together complementary programs, we create a stronger organization that’s capable of delivering even greater support for STEM learning in Kansas City.”

It’s a great union between two STEM-focused leaders in our region, where not only Science Pioneers and Science City benefit, but so do the youth of today right here in the Kansas City region.

<![CDATA[The Miracles of Science Surround Us]]>http://www.labconco.com/news/the-miracles-of-science-surround-us A Meteorological Masterpiece

After a frenzy of meteorological research on how this masterwork of Mother Nature was produced, I called my local TV news station and was rewarded with a five-part scientific explanation for the perfect storm.

Should I really have been looking at the clouds while coaching my son’s baseball game? I frequently chide our players when they get distracted chasing fireflies in the outfield, fooling around with their hats, watching ant hills, counting airplanes, cheering for another game on an adjacent field, or any one of the 4,927 things that they are doing except for paying attention to our game on our field.

Yet there I was, mesmerized by a spectacular, distant sunset lightning storm.

As luck would have it, we were stuck with an 8 p.m. game that night. Since we were well into summer, we were blessed with the sunset behind the outfield fence during our game. And I mean we were blessed because first, we had the beauty of playing the game during the sunset hours, and second because it meant the temperature would drop from a scorching 103° F to a merely simmering 100° F by the time the game was over.

Ahhh, the little joys we look forward to here in the Midwest during June.

This particular sunset was a peculiarity for all of us, and we could not help but be awestruck. Regardless of weather, we were supposed to be paying attention to the ballgame. So I slipped behind the plate during the between-innings warmups and snapped the accompanying photo.

Notice the gorgeous color of the sunset and the striations of the light coming almost straight out from the behind the left cloud wall. We could see on our weather apps the effects of a fairly substantial thunderstorm about 75 miles west of us in Topeka, Kansas.

None of us had ever seen the sky essentially cut in half.

What my still photo doesn’t fully capture is that the left half of the sky was a giant lightning storm way off in the distance. The incredible amount of lightning was giving us quite a show. We could tell something was brewing out there, which we are accustomed to in June here in Tornado Alley.

Here is an interesting radar image of what exactly was going on at the time:

This is a long-range radar image of the wide Midwestern area two minutes before I snapped the image above. You can see the major red cell parked almost on top of Topeka.

It also gives perspective to the distance between the Storm in Topeka and our location in Lee’s Summit, Missouri, just southeast of Kansas City.

According to many Kansas news stations and weather reporting websites, several areas in-and-around Topeka, KS reported hail up to 1.25” and about 9000 people lost power during the storm that night. During our kids’ baseball game we were convinced we would get rain in our hometown, yet within two hours, that large cell had moved well south of our area. We didn’t get a single drop of the rain we thought was sure to come our way.

While the radar images are cool, I really wanted to understand what made that very distinct slice across the sky during that sunset. I tried searching around some weather websites, NOAA and others to learn more about storms and cloud formations; but I really could not find that magic bullet that could explain this one specific thing that we saw that night. Then it hit me: “Ask a meteorologist!”

I called one of the local TV stations and they put me into the voice mailbox where I was sure my message would flounder. In less than 10 minutes Jesse Hawila, one of the meteorologists from KCTV5, called me back and said, “I think I know which night you are asking about because we were all having a great time with it here in the studio as well because of how unique it was.”

He explained that essentially the visual phenomena was caused by the storm’s incredibly high cloud top (50-55,000 feet high), coupled with distinctly clear western sky behind that storm cloud, combined with the perfect angle of the setting sun - because of the time of year and the position of the sun in the sky.

The storm cloud was basically completely isolated in the sky and the setting sun had a direct path to that storm cloud, causing the storm cloud itself to actually cast a shadow, which formed that sharp line that we saw across the sky from our side. He said it was an “A+B+C+D+E situation” where all those factors had to line up perfectly, so it was very cool that we all we able to witness it.

Jesse was also kind enough to send me the following visible satellite image of the storm cloud itself during sunset that same night. He wanted to point out the completely clear skies in western Kansas, the giant storm cloud itself, and then the clear skies again across Kansas City and Missouri. Again, this is a satellite image of the clouds… not a radar image of the rain.

Simply Amazing!

<![CDATA[How to Freeze Dry the 6 Most Challenging Samples]]>http://www.labconco.com/news/how-to-freeze-dry-the-6-most-challenging-samples Lyophilization, or freeze drying, is a technique often used in university and life science laboratories. During the freeze dry process, sublimation occurs as a result of a cycle of:

  1. prefreezing,
  2. primary drying
  3. and secondary drying.

It's a technique well suited for sample preservation, restoration of water-damaged items and—of course—an ever-important vehicle for sample prep.

Sounds simple enough, right? Of course there's much more to freeze drying and we've covered that in-depth on more than one occasion.

Our focus today will be on what goes wrong, not what goes right.

Say you know how to properly care for your freeze dryer and religiously stay away from common lyophilization mistakes (like not knowing your sample's eutectic point, for example).

Why are there still some samples that remain challenging time and time again? What happens when you do everything right and your sample still makes you sweat?

Don't kick your freeze dryer. (Seriously, please don't kick it. We wouldn’t know how to explain that service call.)

Let's examine six challenging samples and discuss what you need to know as you work to lyophilize them.

Challenger #1: Tert Butyl. Before you curl your fists in anger to Tert Butyl's gummy consistency after lyophilizing, here are a few soothing words: It's not your fault. (I repeat: It's not your fault.)

While the compound looks like a perfect freeze dry candidate on paper, our experts have received many customer calls about the output having a gummy consistency—and, unfortunately, that's simply going to happen when you're working with Tert Butyl.

As you work through the lyophilization process, know that you're likely not going to make it all the way to a dry powder.

View our available Freeze Dry Systems

Challenger #2: DMSO (Dimethyl Sulfoxide). Because DMSO has a very high boiling point, it's hard to evaporate in a standard evaporator. Freeze drying, then, should be the perfect alternative, right? Well, it is—but it will eventually attack different components of your freeze dryer.

For example, you'll need to replace the rubber and plastic pieces, as they're apt to show wear pretty quickly when working with this compound. Also, for applications using DMSO, make sure your system has a glass lid to help lessen the replacement burden.

Challenger #3: Alcohols. Alcohols (like methanol and ethanol) have a very low freezing point, so they present a temperature differential conundrum.

Ethanol, for example, freezes at -117°C. Because it's not possible to get a freeze dryer with a collector temperature of -137°C, you must dilute these substances to 10 percent or less by adding an aqueous solution. Then, you can use a -105º freeze dry system to complete your work. Note that if you're working at all with acids, opt for the system with the corrosion-resistant, PTFE collector.

Challenger #4: Salts. Just like salt alters the boiling point of water on your stovetop, it alters the freezing point of samples you're trying to lyophilize. In addition, exposure to salt over time will cause stainless steel surfaces in freeze dryers to rust.

If you're going to be working with compounds containing salt, be sure to invest in a cascade-style (-84° or-105° C) freeze dryer with PTFE-coated components to avoid costly damage.

Challenger #5: Sugars. Sugars won't change the eutectic temperature of your sample, but they could ruin your vacuum pump if they pass into the equipment and crystalize there—and, as we all know, a lyophilizer without a working vacuum pump isn't very productive in the laboratory.

You can protect your pump, however, by placing a secondary HEPA filter between the freeze dryer and the pump so that any sugar that bypasses the cold coils gets trapped before it can do any damage.

Challenger #6: Oils. If you're trying to freeze dry a substance with oil, your output will never be an entirely solid powder. The oil in the sample will sublimate first and leave behind a slicker consistency, but this isn't a deal-breaker.

As long as you're lyophilizing for sample prep and don't need your sample for long-term storage, you can get rid of most of the moisture and carry on with your work.

<![CDATA[RXPert Double Filtered Balance Systems & USP <800>]]>http://www.labconco.com/news/rxpert-double-filtered-balance-systems-usp-800 Almost everyone has had a prescription filled by a pharmacy. The process of filling a prescription should be familiar and simple: receive a prescription from your doctor, drive to your preferred pharmacy then hand the prescription over to the pharmacist. After a short wait you will be on your way with medicine in hand.

  • But what happens when a patient requires a drug dosage or drug that isn’t widely manufactured by a pharmaceutical company?
  • Must a patient settle for an inappropriate dosage or delivery method?
  • What if an extra milligram here or there could mean the difference between healthy and a hive outbreak?

Patients that require specialty medications can fortunately rely on compounding pharmacies.

And there are more than a few of these sites that specialize in the custom preparation of drugs. An estimate by the IACP (International Academy of Compounding Pharmacists) found that nearly 7,500 U.S. pharmacies offer compounding services.

Although largely beneficial to patients – many receive hormone replacement therapies and chemotherapies from compounding pharmacies – these specialty sites have gotten a bad rap in the last few years. In the most notable instance, a batch of sterile injections were contaminated with bacterial meningitis at New England Compounding Center, killing 64 patients.

Browse through our USP <800> compliant Double Filtered RXPert Line.

As a result, State and Federal compounding pharmacy regulators have tightened rules for compounding pharmacies. These regulations are largely derived from the United States Pharmacopeia (USP), a best-practices organization that has written numerous chapters that cover topics from storage of drugs to the proper use of water and beyond.

The new changes do more than just protect patients. Compounding pharmacy personnel also have to follow new regulations to protect themselves from exposure.

Labconco has developed a new balance enclosure, the RXPert Double Filtered Balance System, to comply with the unique, new language found in chapter <800>.

Among the new requirements is double exhaust HEPA filtration for any enclosure designed to recirculate its air back into the facility.

Based on the design of the XPert System, the Double Filtered RXPert performs well beyond USP’s double HEPA requirement by offering an industry-exclusive capability to leak-scan both HEPA filters in the unit. This assures compounders that they are working free of exposure to hazardous drugs.

The additional HEPA filtration embraces the spirit of USP <800> by providing operators with peace-of-mind and safety when handling hazardous drugs.

The pharmacy world is still dominated by major chains, but don’t be too surprised if you see an RXPert (or a variety of other Labconco equipment!) on your next visit to a compounding pharmacy.

Check out our USP <800> compliant Double Filtered RXPert Line.

<![CDATA[Discovery Hall Project at University of Arkansas Opens Doors for Students, Faculty]]>http://www.labconco.com/news/discovery-hall-project-at-university-of-arkansas Nestled in the bustling community of Fayetteville is the University of Arkansas, an educational institution home to almost 27,000 students and countless other faculty and academic leaders.

Fayetteville was voted one of America's most beautiful cities in 2012, and—with the help of an ongoing laboratory remodel project at the U of A—is now home to yet another building of which it can be proud.

Discovery Hall, a multi-level, multidisciplinary space dedicated to chemistry teaching labs and bio-anthropology and archaeology, has been undergoing renovations for some time and is slated for completion in January 2017.

Project leaders adopted an extended timeline for Discovery Hall for good reason: the facility has been open for classes throughout its renovation—an accommodation necessity for the seventh fastest growing university in the nation. Since the project began around seven years ago, the university has experienced a 150 percent increase in enrollment.

The transition of Discovery Hall from a dated building to a modern teaching and learning facility has progressed along with this growth.

"This 1960s building will now be a 2017 building inside and out, ready to serve our students another 50-plus years," Mike Johnson, Associate Vice Chancellor for Facilities, said. "We still spent less than what a new facility might have cost by likely 35-45 percent, and we have a modern teaching facility without losing any real class time throughout the process."

New Hoods, New Capabilities

Fume hoods are essential in chemistry teaching labs, but not all fume hoods are created equally. Discovery Hall designers knew that as they looked to replace or add the total of 76 fume hoods required in the 49,800-square foot space.

Many of the 76 are Protector XStream Hoods, high performance hoods that blend efficiency, safety and functionality. Operating a 6-foot Protector XStream Hood at 60 fpm face velocity with the sash fully open, for example, requires only 690 CFM—an impressively low yield that results in significant energy and budgetary savings over time.

"The design team specified Labconco's XStream Hoods because they were proven low flow hoods that had been used on another project out at the Incubator Campus (Research & Technology Park), and they were advised the U of A wanted to standardize their hoods for operations and maintenance purposes," James Milner, Facilities Management Construction Coordinator for the project, said.

Learn more about Protector XStream Hoods now.

A Better, Safer Space

Replacing and adding fume hoods—and entire lab spaces, to that end—is just one element of the Discovery Hall project. To reach the overall goal of producing a safer, more useful space, many additional changes have been made.

For example, fire and smoke alarms have been replaced, electrical primary and secondary services have been modernized to meet current electrical code and asbestos has been abated from the building.

Substantial upgrades in air handling have also been made, including the replacement of makeup air systems, fan coil units, exhaust and control systems. In addition, fixed benches will soon be added along Discovery Hall's corridors to prevent students from extending their legs into the walkway, causing obstructions.

The new labs and additional hoods have greatly increased the student capacity in the building—but Discovery Hall doesn't just have more labs, it has better labs. Worn, stained casework has been replaced with state of the art systems that include epoxy surfaces. All instructional spaces feature AV systems to promote collaborative learning.

All of the chemistry and biology lab and prep spaces now have compliant emergency eyewash and shower stations, and the number of data outlets has more than doubled since construction began.

Building Wi-Fi has been installed along with whiteboards where archaic chalkboards used to be. The insulation, finishings, roof, windows—you name the face-lift, and Discovery Hall has had it done, all while allowing academic classes to continue as scheduled.

"If we hadn't renovated this building, lots of people couldn't take chemistry because we just didn’t have the space to teach them," Wesley Stites, Chair of the Department of Chemistry and Biochemistry, said. "At the worst point, we were running labs from 7:30 am until 10:30 at night and then more on the weekends. Since we've added labs, it's gotten back to normal and brought accessibility back to the program."

<![CDATA[Just How Precise is the Precise® Glove Box?]]>http://www.labconco.com/news/just-how-precise-is-the-preciser-glove-box WEIGH THE EVIDENCE

Labconco offers two rotational molded polyethylene-lined glove boxes with HEPA filtration: the Precise® HEPA-Filtered Glove Box and the XPert® Weigh Box. Both of these boxes have a built-in blower and inlet/outlet HEPA filters to remove hazardous particulates.

In addition, the XPert Weigh Box features a balance vibration isolator (a marble slab with stainless steel cover and four isolation pads) and an anti-static ionizer fan to control static charge.

A common application for either of these glove boxes is weighing hazardous powders using an analytical balance. We know that Precise Boxes contain and isolate hazardous particulates down to 32 ng/m3 through 3rd party testing confirmed by SafeBridge Consultants, Inc.

But how accurately can an operator weigh drug powders on an analytical balance in a Precise Glove Box with an on-board motor? Labconco engineers put the following performance goal to the test:

“The Precise HEPA-Filtered Glove Box shall permit weighing of samples to five decimal places with an analytical balance without affecting the balance performance. The glove box operational airflow volumes shall allow the precision and accuracy as specified by the manufacturer of the analytical balance.”

Equipment Used in the Test:

  • Precise HEPA-Filtered Glove Box, Catalog #5220200
  • Balance Vibration Isolator, Part #5234600P
  • Marble Slab
  • Type 304 Stainless Steel Cover
  • Four Isolation Pads
  • Mettler Toledo AX105 Delta Range Analytical Balance

Find the Right Filtered Glove Box for your Application

Balance Stability Test Parameters and Procedure

The Mettler Toledo AX105 Delta Range Analytical Balance was placed inside the Precise Glove Box atop the Balance Vibration Isolator. The glove box was located in a typical laboratory setting. No effort was made to isolate the box from foot traffic or other laboratory equipment operating in the room.

The testing consisted of weighing calibration weights (20 mg, 200 mg and 2 grams) five times. After each weighing, the weight was removed and the balance allowed to return to zero. The measurements were taken with the glove box blower off and at settings of 13, 20, 61 and 100 cubic feet per minute (CFM).

Using the identical sampling procedure, the same test performed but without the Balance Vibration Isolator. The Mettler AX105 Balance was placed directly on the interior surface of the Precise Glove Box.

The Results

The five weigh-outs for each target weight were averaged, then the standard deviation and relative deviations were calculated. Complete test data may be found in the Precise HEPA-Filtered Glove Box and XPert Weigh Box Test Report.

Below are the summaries of results for the test performed with the Balance Vibration Isolator and the test performed without the Balance Vibration Isolator.

Precise Test 1: Analytical Balance Stability Test Results, Precise HEPA Filtered Glove Box with Balance Vibration Isolation (Marble Slab)

Precise Test 2: Analytical Balance Stability Test Results, Precise HEPA Filtered Glove Box without Marble Slab

The performance goal was met: the Precise HEPA-Filtered Glove Box delivers precise, reproducible weighing. Balance stability testing on the Precise HEPA-Filtered Glove Box confirmed that it permits weighing of samples with an analytical balance to five decimal places. In both tests, the relative standard deviations were extremely low, indicating that the analytical balance remained stable inside the box.

The results of the test using the marble slab were only slightly better. Neither airflow through the glove box nor vibration from its mechanical components significantly affected the weight measurements, indicating that the Precise Glove Box is inherently stable.

<![CDATA[How to choose the right laboratory glassware washer]]>http://www.labconco.com/news/choosing-the-right-glassware-washer If you've never purchased a laboratory glassware washer before, or if it's been a long while since you have, there are six things you should consider before choosing one:

  1. Resources
  2. Conservation
  3. Form
  4. Function
  5. Your laboratory's specific needs and
  6. Price

Here are some tips and guidelines to the benefits, features and options that are out there.

Loss prevention: time, effort and resources

Hand washing glassware always carries a risk of glass breakage or worker injury, and either can be costly to a lab. Glassware washers help eliminate that risk by greatly decreasing the time a worker is handling the labware. Flasks, beakers, test tubes and petri dishes are fragile resources. Other things to consider are the economics of energy and related costs, the washer's footprint, performance, flexibility and durability.

The "Green Scheme": saving energy and water

Energy costs and water conservation are hot topics. People are trying to be more environmentally responsible, and glassware washers can definitely fit into the “Green Scheme.”Hand washing 30 pieces of glassware takes about 20 gallons of tap water (EPA Water Trivia Facts). A good glassware washer should use less than 14 gallons of water to wash the same amount of glassware. This translates into a savings of about 1,664 gallons of water per year.

While water conservation is a great green feature, energy saving features like a delayed start are popular options. A delayed start feature allows the user to wash during off-peak hours when energy costs can be lower. You could see up to a 50% savings in energy costs annually.

In addition, Labconco FlaskScrubber and SteamScrubber Washers are made of 51% recycled material and 77.6% of the washer can be recycled.

Glassware Washer Selection Tools

Quickly find out how much you could save using our glassware washers. You can also configure the perfect washer for your laboratory space.

 


Consider your space: Form over function

Before selecting a washer, know your space. Define the final location of the washer. This will help you determine the best configuration to fit your needs. Undercounter models (which include a standard height or ADA height version), freestanding, and mobile units are readily available. Do you need extra storage? Base stands are available, and handy not only for storage, but also they raise the washer up, requiring less bending when loading and unloading glassware and other accessories.

Raw performance: Function over form

When it comes to washer performance, it’s important to know what functionalities the washer is capable of performing. Dual pumps are a highlyimportant feature to look for in a washer. Having a separate pump that brings in clean water and one to remove dirty water reduces the risk of cross contamination. Cross contamination can be very costly to a lab - be aware that some washers do not have separate pumps. 

Washing cycles also vary from manufacturer to manufacturer so compare the cycles that are preprogrammed and determine whether or not they can be altered. Are there user-defined programs? Can programs be password protected? Are there low or high heat options for different types of labware? Make sure the washer is capable of getting your type of labware clean.

Now that it's all clean, how does the unit dry? Can it dry the outside and inside of the glassware? Labconco washers use forced air drying throughout the chamber, and in the FlaskScrubber models, forced air will jet through the spindles of the lower spindle rack, drying the inside of narrow-necked glassware.

Identifying your specific needs

Flexibility of a washer is important. Make a point of knowing if the washer can take the types of labware and utensils you use. If you cannot easily fit your labware in the washer, is it worth the expense? Of course not! Identify what types of glassware you want to wash. Are they wide-mouthed beakers or petri dishes?

Inserts and accessories can be added to customize the washer’s standard racks to accommodate your particular glassware mix. What about narrow-necked glassware such as volumetric or Erlenmeyer flasks? Washing flasks requires special features like those found in a FlaskScrubber that has the capability of injecting water into the deepest part of the flask to thoroughly wash the glassware.

The message here is that not all glassware is cleaned in the same way, so accessories may be required to customize for your specific needs.

For help finding the right inserts and accessories for your lab, try this article: 
5 truly lovable Glassware Washer Accessories

Getting the best deal

Laboratory washers can bear a heavy price tag so knowing how long one will last is important. Residential dishwashers are made to wash cereal bowls and dinner plates, not laboratory glassware. Materials of construction on a residential unit cannot withstand the laboratory chemicals nor the high heat required in some wash cycles (not to mention the fact that dishwashers generally can’t heat the water to reach the required temperature).

Using a residential glassware washer in a laboratory negates any warranty that may have come with it. Labconco's glassware washers offer a 2-year warranty. Don’t forget the importance of the dual pumps laboratory washers offer. Dishwashers have a single pump…dirty and clean water is moved with the same pump. Also, laboratory washers generally have an option to bring in purified water, DI or RO, for final rinsing, a feature not seen in a residential washer.

The Labconco line of laboratory glassware washers come with a pure water pump so that the water source does not have to be pressurized.

For more specifics on why residential dish washers are insufficient for cleaning glassware, try this article: 
5 reasons NOT to use a residential dishwasher to clean laboratory glassware

Lastly, when comparing washers head to head, inspect how a washer is priced. Some manufacturers sell washers as a shell unit that does not include any racks, shelves, certain pumps, and accessories. Labconco laboratory glassware washers include at least one rack, depending on the model, and all come with a dedicated pure water pump. Be sure to understand what features are standard on each unit as well as the associated costs that you could incur to add accessories or racks needed.

You may be disappointed by choosing a washer based solely on price, discovering upon installation that you don’t have racks or accessories needed to use the washer. Make a checklist of all the features that you need, then figure out what is standard with the washer or if the extra feature/s would be additional costs on the models you are considering. You might be surprised by the difference in price when you add in all of the accessories needed to actually wash your labware.

If you have any questions contact us. We are happy to help you find the glassware washer for your application.

<![CDATA[7 Questions to Answer when Choosing a Fume Hood]]>http://www.labconco.com/news/7-questions-to-answer-when-choosing-a-hood Choosing a fume hood can seem like a daunting task. There are so many options to choose from and so much information to gather in order to make an informed decision. But fear not, help is at hand!

First, spend a few minutes answering these questions. When you have answered all seven questions, you will have successfully established the criteria necessary for choosing a fume hood system.

Second, review the answers with a Labconco Application Specialist, and we will make the best product recommendations based upon your answers.

If it helps, please print this story to use as a checklist before ordering. 

1.     What will you be doing inside the hood?

Try to document as much as you can about the application. What chemicals are used, and how are they used? Is heat involved? What volumes of chemicals will be used at a given time? Most importantly, know the answers to the following questions:

  • Do you use Perchloric Acid?
  • Do you use Hydrofluoric Acid (HF)?
  • Are you working with Radioisotopes and require the use of lead bricks?

2.     What size of fume hood do you need?

This is a four-part question:

  • How wide do you want the fume hood to be?

Labconco offers fume hoods from 30 inches wide to 16 feet wide, with many options in between. 

  • Will there be equipment enclosed in the hood?

If the answer is yes, then you must answer:

  • What are the dimensions of the equipment?

This information is essential to determining how deep the hood needs to be to house your equipment.

  • Do you need a bench-top or floor mounted hood?

Applications that use extra-large equipment, such as 50-gallon drums, or applications that require equipment to be wheeled into the hood via a cart would require a floor mounted hood.  

3.     Do you require service fixtures or other accessories in the fume hood?

These include (but are not limited to) airflow monitors, electrical outlets, compressed air, laboratory gas, vacuum and cold water fixtures. Gooseneck faucets are also available. Finally, do the fixtures need to be factory installed, or will the installer handle that at the job site by using field-installed kits?

4.     What about required accessories outside of the fume hood?

  • Do you need a work surface and base cabinets, or will you be using existing casework to support the hood? 
  • If you do need base cabinets, do you need acid storage, solvent storage or non-chemical storage?
  • Do you need ductwork from the hood to the roof, or will your HVAC contractor provide it?

5.     How will the fume hood be exhausted?

Every fume hood needs a blower, and it is often misconceived that a blower comes attached to a fume hood.

Will there be a dedicated blower (exhaust fan) for this hood, or will it connect to a central exhaust system?

If it connects to a central system, will it be constant volume or variable air volume?

If you already have a blower, and it is sized appropriately, you can stop right here: Give Labconco a call and we can finalize your fume hood selection!

6.     Do you need a built-in blower or a remotely located blower?

Built-in blowers are easier to install (and therefore less expensive), but they can be noisy and they put the ductwork under positive pressure, so they should be reserved for non-hazardous applications, short duct runs and instances where a remote blower cannot be installed (such as a mobile lab).

Remote blowers, though more complex to install, can be sized for the specific situation and keep the ductwork under negative pressure for safer operation.

7.     What is the layout of the duct run?

Will the duct go directly to the roof, or does it need to make some turns before reaching the roof? What diameter of duct will be used? Once the duct penetrates the roof, a final 90-degree elbow will be needed to turn the duct horizontal, then three to five feet of straight duct is needed between the elbow and blower.

Finally, the exhaust stack should include a zero-pressure weathercap (not a gooseneck, mushroom cap or anything that would block the exhaust from discharging in a vertical, up direction), and should terminate at least 10 feet above the roofline to allow the fumes to reach the airstream and not be returned into the building’s air handling equipment.

--

After you have all of these questions answered...

Contact Labconco and we will find the right fume hood for you!

<![CDATA[How to Properly Care for your Freeze Dryer]]>http://www.labconco.com/news/how-to-properly-care-for-your-freeze-dryer As is the case with all categories of laboratory equipment, the longevity of your freeze dryer depends on how you use it (application), how often you use it (frequency of use) and how well you care for it (maintenance).

While it is true that some freeze dryers continue to lyophilize effectively for decades, the average life span of a freeze dryer in today's laboratory environment is approximately 10 to 15 years.

Do you want to know the secrets to getting that much life out of your freeze dryer?

Let's break down application, usage and maintenance—all those factors that determine how long and how well your freeze dryer works—and identify several Do's and Dont's to guide you.

DO . . .

Make sure your freeze dryer is compatible with the eutectic temperature of your sample(s).

First and foremost, ensure your sample is compatible with your freeze dry system before you use the unit. A good rule of thumb is to plan for your most challenging sample and choose a system based on that need.

It's not possible to modify a freeze dryer’s condenser temperature.

The condenser temperature should be 10 to 15°C below the sample’s eutectic point. Low freezing point solvents, for instance, should not be used on -50°C units.

Certain acids should not be used with bare stainless steel and should only be used with PTFE models. Systems that reach -84°C are ideal for lyophilizing samples with low eutectic temperatures (like those that contain acetonitrile).

Systems that reach -105°C can handle samples containing small amounts of ethanol.

Perform regular vacuum pump maintenance.

Have you ever had problems with your freeze dryer not pulling sufficient vacuum?

If so, you're not alone—it's one of the most common freeze dry troubleshooting issues. The good news is that performing regular pump maintenance can help solve the problem, both reducing immediate downtime and increasing unit life in the long term.

After you’ve ensured you have the appropriate lyophilizer for your samples (see above), do the same for your pump: standard rotary vane pumps work well for aqueous based solutions, and hybrid or combination pumps are best suited for use with solvents or acids.

A low maintenance option, the scroll pump, is a new offering, which does not use oil at all.

In some cases, secondary acid or solvent traps can be used to extend the life of your vacuum pump by providing an additional barrier between the lyophilizer and the pump.

Dry ice traps are also available if you don't have the appropriate temperature differential between the eutectic temperature of your sample and the collector temperature.

Last but certainly not least, make sure to change the oil in your vacuum pump every 1,000 hours (or sooner if your application warrants). If in doubt, check the appearance of the oil. If it's cloudy or darker than an iced tea color, it needs to be changed.

Note that some pumps, such as hydrocarbon free scroll pumps, can pull a deep vacuum for freeze drying without using oil. If you've chosen a scroll pump, make sure to change the scrolls after every 40,000 hours of use.

Clean the freeze dryer after each run.

It's necessary to defrost and drain the condenser after each standard run.

If using acids, note that you'll also need to neutralize the chamber.

Regardless of the sample used, you must rinse and wipe down any components that may have come into contact with chemicals to reduce the risk of damage. Don't let water—especially chemically contaminated water—sit on the stainless, acrylic or rubber components of your freeze dryer.

DON'T . . .

Put samples in the freeze dryer that aren't completely frozen.

A sample must be completely frozen to be included in a lyophilization run. If it's not, a large volume of the sample will evaporate, thereby producing a high initial vapor load.

The vapors can then pass through the condenser and into the vacuum pump where they can do damage. Or, in worst-case scenarios, liquid could be sucked directly into the pump, causing even more damage.

Note that if a sample starts to melt back in-process, simply make adjustments so that is remains frozen or remove it from the system entirely.

Overload your freeze dryer.

Overloading your freeze dryer can make sessions last longer or even cause them to be wholly unsuccessful. The vapor load that the condenser must accommodate is the greatest when a sample is first loaded. 

The instantaneous load capacity rating is the quantity of vapor a freeze dryer can accommodate at one time. This is a different measurement than the ice holding capacity or the 24-hour collection rating.

When freeze drying multiple, large volumes, make sure the condenser temperature does not rise shortly after the sample is loaded. If this does happen, you are close to exceeding the instantaneous load capacity. In these instances, consider staggering the loading so samples are started at varying intervals.

Neglect maintenance.

At the end of a run, it's easy to remove your completed samples and forget to defrost and drain the condenser—an act that not only lengthens the process for the next user but can also cause damage to the unit if done frequently.

Maintenance is important for vacuum pumps, too. Although it can be time consuming, changing the oil frequently is a must. Especially when there are multiple users of a single system, keeping a maintenance log of oil changes and compressor cleanings can help ensure none of these crucial tasks are neglected.

<![CDATA[Adding Efficiency to Labs]]>http://www.labconco.com/news/adding-efficiency Energy efficiency in a lab can be worth thousands of dollars of savings per year. Equipment such as a single fume hood can use the equivalent energy of three and a half single family homes per year [1] making energy efficiency a priority for labs.

This article talks about a few things labs can be mindful of in order to keep their bills in check, including a special shout-out to Labconco for the Intelli-Sense Multi Speed Blower. This blower is meant for use with small labs that want a night set-back option for their fume hoods, and do not have the resources to sustain a VAV system.

So instead of going with rules of thumb, check out how laboratory equipment can work towards real energy efficiency.

Sometimes the latest equipment in a laboratory, say a next-generation sequencer, grabs lots of attention, but it’s the workhorses—centrifuges, hoods, freezers, incubators, and more—that keep experiments and workflows moving...

<![CDATA[5 Questions to Ask when Selecting a Concentrator]]>http://www.labconco.com/news/need-help-selecting-a-concentrator We often are asked many questions regarding Labconco CentriVap® Concentrators. Here are the answers to some of the most common questions.

If your question is not answered, do not hesitate to contact us as we are happy to help. Expert advice is only a phone call, email or chat away.

1. Why are concentrators used for evaporating biological samples?

The most common way to evaporate something is to apply heat and boil off the liquid. Biological samples are heat sensitive thus the heat that drives the evaporation process must be limited. In a vacuum atmosphere pressure levels are lowered and liquids boil or evaporate at lower temperatures.

A vacuum atmosphere in the concentrator lowers the pressure level so that evaporation will occur at low temperatures and the samples will not be damaged from heat.

2. How are concentrators different than centrifuges?

Both concentrators and centrifuges spin samples that are commonly in tubes or microplates. Centrifuges spin samples at variable rates creating G forces that separate samples according to density. Concentrators spin samples at a fixed, low-speed that creates just enough force to keep the liquid samples in tubes or microplates so a vacuum can be applied to liquids without losing any samples. Concentrators require a vacuum pump and centrifuges do not operate under vacuum.

3. Does every Labconco CentriVap® Concentrator need a vacuum pump?

A vacuum pump is required to centrifugally concentrate, however the CentriVap Micro IR, CentriVap DNA and CentriVap Complete models include a built-in chemical-resistant diaphragm vacuum pump and a rotor. All other CentriVaps require the purchase of a chemical- resistant diaphragm vacuum pump.

4. When do you use a cold trap with a concentrator?

Most samples do not require a Cold Trap in order to evaporate.

  • Cold traps are needed to create a closed system, meaning all of the solvents that are being evaporated are collected in the cold trap. This is helpful if the lab does not have a fume hood to safely exhaust the evaporated solvents. 
  • If a rotary vane (oil) vacuum pump is being used with the concentrator, a cold trap is required to protect the vacuum pump by collecting the liquids and vapors before they reach the vacuum pump.
  • If the lab would like to lyophilize in addition to concentration then a cold trap is needed as well as a vacuum pump that can produce a sufficient, deep vacuum.
  • If a cold trap is not being used when concentrating large volumes a glass trap should be inline before the vacuum pump to collect any liquids that are condensing in the vacuum tubing before they reach the vacuum pump.

5. Is there an easy way to determine which Labconco CentriVap® Concentrator is best for my applications?

Labconco offers an extensive selection of centrifugal concentrators with each model designed for specific applications. To ensure you are getting the best CentriVap for your needs, simply use the Scout™ Lab Equipment Selector on the Labconco website.

<![CDATA[The Protector Echo proves itself]]>http://www.labconco.com/news/the-protector-echo-proves-itself The Echo Passes Third-Party Testing

During the development of the Protector Echo Filtered Fume Hood, the design engineers decided to challenge the Echo with not one, but four different third-party containment tests. Why?

It’s simple, really - to ensure containment was going to live up to the Labconco standard. These tests ranged from the standard ASHRAE 110 containment test, to a challenging modified containment test with adverse conditions to truly test its limits.

What is the Echo?

The Protector Echo is a completely new fume hood added to the Labconco line-up. It’s different because it does not require any ductwork to function.

Instead, it is a filtering fume hood that will filter out the contaminated air and exhaust the clean air into the laboratory, making it very energy efficient.

It was designed with superior containment in mind, using all of Labconco’s highly engineered high performance fume hood features.

All of the features that make Labconco’s ducted fume hoods effective provide the same protection on the Protector Echo. The Clean-Sweep™ sash handle and Clean-Sweep™ sash track improve containment, along with the Eco-Foil™ air foil - an aerodynamic sill designed to correct the naturally occurring turbulence at the threshold of a fume hood.

The Results

During independent testing*, the Protector Echo Hood was challenged well beyond the SEFA-1† standards.

The Echo was subjected to both the standard ASHRAE 110 test using Sulfur Hexafluoride (SF6) tracer gas test while attached to a canopy, as well as the modified ASHRAE 110 test with no canopy connection, using Isopropyl Alcohol (IPA) to replace the SF6.

And to go above and beyond, the NIH protocol was used – which means that during the test with a canopy, the SF6 release rate was increased to six liters versus four liters per minute in the standard ASHRAE 110 test, the hood was filled with paint cans and boxes and rapid walk-bys were incorporated.

In all scenarios, the Protector Echo allowed 0.00 ppm average level of tracer gas outside the fume hood.

This allows us to conclude that for those customers who cannot duct out of their building, or for those who want to save on energy costs and use filtered fume hoods in lieu of or alongside ducted fume hoods, this enclosure will present a safe alternative.

<![CDATA[Creating a culture of safety]]>http://www.labconco.com/news/creating-a-culture-of-safety Q & A with Industry Expert Sean Kaufman

Safety in the workplace is important regardless where you clock in every day, but it's especially important to master when your professional environment regularly contains hazardous particulates, harmful chemical vapors or radionuclides.

Even basic microbiological work has some associated risks, as oftentimes it is not only necessary to protect the person sitting at the face of the cabinet but the science taking place inside on the work surface. It's with this eye toward protection that laboratories have rightfully turned to employing the use of biosafety cabinets, allowing their technicians to properly and safely handle biosafety agents requiring BSL 1-3 containment.

That just scratches the surface, so we decided to dig a little deeper and get the input of an outside industry expert to talk about the true meaning of creating a culture of safety for biosafety in laboratories and how that relates to leadership.

That expert is Sean Kaufman, CEO of Behavioral-Based Improvement Solutions. Sean's approach to the biosafety industry is truly safety-centric, and his knowledge has been called upon in various high profile circumstances including the 2001 Anthrax attacks and SARS outbreak.

He has testified in front of Congress about infectious diseases and, in 2014, prepared the clinical staff at Emory Healthcare to respond to the first cases of Ebola on American soil. He then traveled to Nigeria and Liberia to prepare healthcare workers there to do the same.

So, let's just say Sean knows his stuff when it comes to biosafety. While his background is diverse, his message is simple: safety matters. We jumped at the opportunity to ask him a few detailed questions—read on to learn how to create a culture of safety and why it's important.

---

Q: To start, can you describe a little bit of what you do?

A: I'm a behavioral psychologist focusing on infectious disease. Biosafety cabinets are pieces of equipment—very vital pieces of equipment—but I focus on human behavior with and around them. You can spend thousands and thousands of dollars on a cabinet, but all the control can be negated in an instant with inappropriate behavior. I don't think the need for biosafety cabinets is any longer debated.

  1. They work.
  2. They're efficient.
  3. They're clean.

They're one of the best engineering controls we have in biosafety today. There are lots of complexities, but the workforce needs consistent investment in preparing them to effectively work in a cabinet—that’s where I'm an advocate.

---

Q: Let's start dissecting those complexities. There are so many considerations when it comes to biosafety cabinet selection. How do you begin to conduct risk assessments, and why are they important?

A: That's a big question. When you look at a biosafety cabinet, the first and most basic thing you have to do is determine what you're going to be using it for. Then, decide how much workspace you need.

Ask yourself a few questions:

  • Are you going to be working with animals?
  • What type of connection does your science require—are we talking recirculated A2 or thimble connected A2?
  • Maybe you'll need a fully ducted B?

From a big picture perspective, we look to make sure the cabinet is certified, it is functioning properly and it passes a smoke test. If all those are in check and you've chosen the appropriate equipment, the biosafety engineering aspect has been done for you. Now you must operate safely within the enclosure.

---

Q: So, after selecting a biosafety cabinet, what comes next?

A: It's absolutely critical to train employees because they are the human interface of the biosafety cabinet, of that engineering control. Leaders need to train them how to choose appropriate personal protective equipment and develop standard operating procedures (SOPs) that answer real questions.

How do we set things up and break them down? In my opinion, by the way, the cabinet should be broken down and cleaned at the end of each night.

  • What type of disinfectant are we using?
  • How are we going to deal with corrosives?
  • Are we working from clean to dirty?

The risk assessment list goes on and on, but having effective, tested and validated SOPs is critical throughout the life of the cabinet. When there are standard, easy to follow checklists in place for routine operations, some of those processes can be streamlined and the risks minimized.

---

Q: As a behavioral psychologist, I think you're more qualified than anyone to answer this next question: Do you feel ergonomics play a role in safety in the laboratory?

A: Absolutely—but I have my own philosophy on that.

Leaders do three things:

1. They prepare the workforce

2. They protect the workforce and

3. They promote the workforce.

When you look at the words 'prepare the workforce,' preparing means that they give the workforce the resources they need to do the job and to do it well. That’s where good biosafety cabinet ergonomics come in.

These technicians are dealing with long hours at the bench, and you have to consider posture, arm position and a number of other behaviors that can affect how safe the work actually is.

Adequate preparedness is critical in the workforce, and that's a leadership responsibility.

---

Q: Can you explain in greater depth the role of ideal leadership in the laboratory and how that relates to safety?

A: To me, biosafety cabinets are phenomenal engineering devices. However, the minute they come in contact with a human exhibiting human behaviors, that person better be trained or the cabinet could risk losing its protectiveness. Again, that's a leadership thing. You can't just give someone a biosafety cabinet and say, 'go work.' You have to train them how to use it.

Some technicians tend to over-rely on the engineering aspects of the cabinet. It's great that they're working in them, but they might botch the glove removal process or become lax at disinfecting. That's how we have instances of individuals coming out of biosafety cabinets and contaminating other areas of their laboratories.

The workforce is supposed to follow some very clear expectations. Even if they were to follow all of them, leadership still has a responsibility to the workforce.

Guidelines and policies bring us together, but being together and doing together are very different things. Everyone has to be on-board with safety in order for it to work, and that starts at the top.

Sean Kaufman spoke before Congress on safety in the laboratory as it pertains to the anthrax incident of June 2014 at the Center for Disease Control.

<![CDATA[4 questions to answer when selecting an evaporator]]>http://www.labconco.com/news/4-questions-to-answer-when-selecting-an-evaporat You know that your process will require an evaporator, but how do you decide which one is right for your application? Answer these four questions to decide which evaporator would be the best choice:

1. How hot can my sample get?

“How much heat can be applied to my samples?” is one of the first questions you’ll need to answer.  In many methods, heat is the driving force of the evaporation process. Determining whether your sample is heat-sensitive or not will help narrow down which evaporation method is best for your specific scenario. Typically the evaporation process will involve a vacuum pump if a sample is heat sensitive, so the boiling point can be significantly lowered under the decreased pressure.

Evaporators for extremely heat sensitive samples                           

Evaporators for samples that can be heated-moderate or high

2. What is my sample volume?

The volume of your sample will be an important factor in determining the evaporator that will accommodate your requirements. Some evaporators can accommodate a wide range of sample sizes while others are designed for a very specific size of sample.

Evaporators for very large sample volumes > 250 ml

Evaporators for very small sample volumes < 1.0 ml

Evaporators that accommodate a wide range of sample volumes

3. How many samples am I going to evaporate?

The number of samples that you need to evaporate at one time will determine which evaporator is most appropriate for your application. Various types of equipment accommodate different numbers of samples.

Evaporator Type Maximum # of Samples
Rotary Evaporators 1 sample
CentriVap® Centrifugal Concentrator 132 samples  (1 to 2ml ea.)
FreeZone® Freeze Dryer/Lyophilizer  >2,000 samples
RapidVap® Vertex Dry Evaporator Up to 50 samples
RapidVap® Vacuum Dry Evaporator 110 samples (12 or 13mm tubes)
RapidVap® N2 and RapidVap® N2/48 Dry Evaporator Up to 48 samples (12 to 20mm tubes)

4. In what condition does the finished product need to be?

The condition or state of the final sample is a definite determinate of which evaporator is the best solution for your samples. Are your samples biological? Does their bioactivity need to be preserved for a long period of time? Does your method involve taking your sample to dryness, or do you need to stop the evaporation before the sample is dry? All of these factors need to be considered when selecting an evaporator.

Evaporators that preserve bioactivity and the final product can be a cake that is easy to reconstitute

Evaporators that can dramatically slow evaporation at specific end points

Evaporators with programmable time and heat temperature

<![CDATA[How to select the right vacuum pump]]>http://www.labconco.com/news/how-to-select-the-right-vacuum-pump When it comes to selecting a vacuum pump there are a number of options for choosing the best pump for your application. Vacuum pumps are available in different types that offer varying displacement capacities and ultimate vacuum levels.

There are four main types commonly used in laboratories for freeze drying (lyophilization), evaporation and concentration.

Rotary Vane

Traditional Rotary Vane (RV) Vacuum Pumps are often used because they can have a lower up-front cost, are smaller than other types, and can be used with multiple applications. RV pumps use oil to ensure a tight seal, lubricate the working parts and remove heat to cool the rotors.

Any solvents that are not trapped or recovered before they enter the RV vacuum pump can condense in the pump oil and damage the inside of the pump. It’s necessary when using an RV pump to collect the evaporated vapors upstream of the pump. Condensers or Cold Traps are commonly used to collect these vapors and protect the pump.

Another downside of the RV pump is that the oil must be changed which is a costly process. It is recommended that the oil in these pumps be checked regularly and changed approximately every 3,000 hours of use.

The life of the vacuum pump depends on the maintenance of the oil. While there are systems that automate oil changing, time is still lost while the pump is out of use for the maintenance.

Rotary Vane vacuum pumps reach deep ultimate vacuum levels and have high displacement capacity. This makes them a good choice for freeze drying applications. RV pumps work especially well for aqueous samples and solvents with high boiling points whose vapors can be easily trapped before they reach the pump.

Diaphragm

Diaphragm Vacuum Pumps are dry pumps that operate using a pulsing motion that opens and closes valves to move air. This design eliminates the need for oil. The valves are often made of polytetrafluoroethylene making the pump resistant to corrosives and less susceptible to damage from vapors.

While they can have a higher up-front cost, they do not use any oil so operation and maintenance costs are significantly lower than pumps that require oil. Diaphragm pumps can handle highly viscous liquids and be used with a wide range of samples but the applications are limited to those requiring higher ultimate vacuum levels.

Ultimate vacuum levels of these pumps are not extremely deep and displacement capacities are much lower than other types of vacuum pumps.

Diaphragm pumps are one of the most chemical- and corrosion-resistant types of pumps. Therefore, almost any type of sample, even those containing a combination of solvents and acids can be used with these pumps, making them a good choice for both evaporation and concentration.

A diaphragm pump can’t be used for freeze drying since the depth of vacuum isn’t enough.

Combination (Hybrid)

Combination Vacuum Pumps, also known as Hybrid Vacuum Pumps, have both a Rotary Vane and Diaphragm pump together in the same vacuum pump. In a combination pump the diaphragm pump keeps the oil of the RV pump under negative pressure to reduce or eliminate vapors going through it and condensing in the oil. This design keeps the oil cleaner and allows for less frequent changing – oil lasts up to 10 times longer between changes compared to RV pumps.

So while there may be a higher up-front cost than an RV pump, the operation costs are lowered as less replacement oil is needed and less time is lost changing the oil. The ultimate vacuum level and displacement capacity with combination pumps is similar to those of RV pumps. Because the diaphragm pump is incorporated into the design, these pumps are better at handling acids and solvents than RV pumps.

Combination pumps are recommended for freeze drying corrosive or volatile samples as they can be used with acidic samples and those containing harsh chemicals such as TFA, acetonitrile, HBe and Nitric acid.

Scroll

Scroll Vacuum Pumps are dry pumps that use two spiral scrolls to compress air and vapors and move them toward the exhaust. While they can have higher up-front costs, the lifetime operation costs are much lower because they don’t require oil and very little maintenance is needed.

It is recommended that the scrolls be changed every 40,000 hours of use. By eliminating the oil, the hydrocarbon-free design means these pumps are environmentally friendly as well. Scroll pumps handle water vapor better than most types of pumps and make significantly less noise during operation.

Because the scrolls are made of metal, even on chemical- or corrosion-resistant models, only samples with acids below 20% are recommended. Compared to diaphragm pumps, scroll pumps can reach deeper ultimate vacuum levels and have higher displacement capacities.

Scroll pumps are recommended for freeze drying as they can be used with aqueous and solvent samples including acetonitrile. They may be used with concentration applications also, however the cost tradeoff may make another type of pump more attractive.

In Conclusion

No matter what type of pump you’re using, one of the most important things to remember about vacuum pumps is that whatever goes in the pump will come out! Even with filters, you need to take other precautions when samples include potentially hazardous materials. Venting into a fume hood is required when using hazardous samples.

Labconco offers multiple vacuum pump options and many vacuum pump accessories including the new Scroll Pumps. If you’re unsure which vacuum pump is the best for your application, our Application Specialists are always here to help.

<![CDATA[Axiom Week: Day 5]]>http://www.labconco.com/news/axiom-week-day-5 FAQs, Myths, Fabrications & Misinformation about the Type C1 Purifier Axiom - Part 5

---

What are the Axiom’s advantages over Type B1 and B2 BSCs?

The Axiom outperforms each of the Type B BSCs in regards to safety and flexibility. Though similar in airflow to a B1, the Type C1 does not require special considerations when handling hazardous chemistry, nor does it require a dedicated exhaust system. A B1 BSC cannot operate without exhaust and therefore will always require the infrastructure and cost associated with moving expensive tempered air. The Axiom can be removed from ductwork, eliminating or reducing the cost associated with exhaust air. 

A Type B2 BSC experiencing a remote exhaust failure can pressurize the work zone, pushing contaminated air into the laboratory. The C1 BSC is easily adapted and/or manifolded into an existing building exhaust system, and should there be a failure, it protects the laboratory and the operator for an additional 5 minutes. Type B2 BSCs also heavily tax exhaust systems with large volumes that can exceed 1,200 CFM – this can cost over $100,000 per BSC to operate over its life. The C1 reduces this volume by over half, saving over $50,000 per BSC. 

An A2 can be ducted to handle odors and non-hazardous chemistry and it is easily adapted to exhaust systems. It can never offer the chemical protection of the Type B or C BSCs because it does not have single-pass airflow. 

Type A and Type B BSCs cannot be retrofitted, altered or otherwise made into the other type of cabinet. The Type C1 adopts the strengths of the Type A and B BSCs while addressing their limitations and is cross functional.

Conclusion 

This information is provided to educate and inform life science and biosafety laboratories about their new options in selecting Class II BSCs for varying applications and operations. In summary: 

  1. The designation of the Axiom is currently being reviewed by NSF/ANSI Standard 49. It will be designated something other than a Type A or Type B, will be defined as such, and upon completion will be recognized by NIH, CDC, CFIA, and PHAC. The Axiom is NSF Listed for product and personnel protection when installed in both ducted and recirculating modes. 
  2. The airflow in the Axiom, though similar to other existing Class II BSC types, is different and allows for greater flexibility, operational safety, safety during building system failures, and has a lower price/cost burden. 
  3. Like all Class II BSCs, a risk assessment should be performed in order to select the proper Class II BSC; however, the Axiom simplifies this process by being suitable for any microbiological application requiring a Class II BSC. 
  4. The inclusion of a Bag-in/Bag-out (BIBO) option on the Axiom makes it a suitable replacement for any Type B1 or B2 application and installation. The BIBO option is used for chemical (pharmaceutical) powders and radioisotopes that cannot be decontaminated. 
  5. In both Type A and Type B modes, the 3-piece work area with dished Chem-Zone work surface provides increased safety and efficiency by promoting organized work behaviors and ergonomics. 
  6. The Active Protection Protocol engages only in emergency building exhaust system failures and provides safety to the BSC operator while they complete their emergency shut down procedures. This is done without posing a risk of exposure due pressurization of the BSCs interior work zone (as seen in direct hard connected Type B BSCs), or by directly forcing chemically contaminated exhaust air into a laboratory (as seen in the positive pressure relief flaps of a Type A2s canopy/thimble).

Our final video covers the General Airflow Pattern of the Axiom!

<![CDATA[Axiom Week: Day 4]]>http://www.labconco.com/news/axiom-week-day-4 FAQs, Myths, Fabrications & Misinformation about the Type C1 Purifier Axiom - Part 4

---

Can the Axiom replace a Type B2? 

In most cases, YES! Type B2 cabinets are commonly selected out of an over-abundance of caution related to a microbiology lab’s use of chemicals considered to be hazardous, not out of risk assessment determining that the application is using hazardous chemistry.

MYTH: The Type B2 BSC provides the greatest flexibility because the work zone airflow is exhausted 100%. 

TRUTH: The B2 is the most inflexible of all Class II BSCs because it is 100% exhausted. By NSF/ANSI Standard 49 definition, Type B2 BSCs require a dedicated exhaust system and blower to provide personnel protection.

MISINFORMATION: The Type B2 does not require specific use work instructions because of its 100% exhausted work zone. 

TRUTH: The Type B1 is the only cabinet that requires specific and special training/user work instructions, to assure that users work in the appropriate area of the BSC’s work zone. For the A2, A2 with canopy, B2 and C1 – users simply work inside the dished work surface. 

NOTE: It is always safe practice to work in any ventilated safety enclosure as far from the open face as possible. As cited from the BMBL 5th ed. by NIH/CDC, Appendix A – in reference to BSC usage, “All operations should be performed on the work surface at least four inches in from the front grille.” 

FABRICATION: As with all volatile chemical use in BSCs, a risk assessment must include worst case scenarios of spills and container breaches to evaluate worst case exposure scenarios.

TRUTH: The use of volatile chemicals cannot be lumped into all-inclusive scenarios. All applications should be vetted by the Biosafety Officer (BSO), Industrial Hygienist or EH&S Official for risk assessment. 

That risk assessment should also include laboratory risks during system failures – especially the building exhaust system. 

During a remote exhaust failure, Type B BSC must detect an exhaust remote failure within 15 seconds. During this time the BSC is pressurized and the user is in the path of air from the work area back into the laboratory, characterized as “puff-back” – as defined by NIH/CDC in the BMBL 5th edition.

BENEFITS: In a B2, the entire work surface is capable of containing hazardous chemical vapors. However, since the B2 must have a dedicated exhaust system, the cabinet is forever committed to its installation. Not at all flexible.

The Axiom’s Omni-Flex capabilities make it the most flexible BSC design. This is possible because the cabinet does not exhaust 100% of its air and does not need a dedicated exhaust system.

During a remote exhaust failure the Axiom can protect an operator for up to 5 minutes while they complete shutdown procedures and secure their laboratory assets.

ADVANTAGE: AXIOM

MISINFORMATION: The Axiom does not have an NSF listed safe change bag-in/bag-out option for the exhaust HEPA filter. 

TRUTH: The Axiom’s NSF listing at http://info.nsf.org/Certified/Biosafety indicates that the Axiom is approved with the following NSF approved accessories:

  • I.V. Pole 
  • U.V. Light 
  • Bag-In/Bag-Out 
  • Cord & Cable Portal

<![CDATA[Axiom Week: Day 3]]>http://www.labconco.com/news/axiom-week-day-3 FAQs, Myths, Fabrications & Misinformation about the Type C1 Purifier Axiom - Part 3

--

Can the Axiom be easily changed from room recirculating to exhausting (or vice versa)?

Yes, the Axiom can be changed from Type A mode to B mode in 4 steps. Though there are laboratory balance considerations, modern laboratories outfitted with VAV and lab balance mechanical systems can easily handle the volume of air this entails.

MISINFORMATION: In regard to ventilation, laboratory building requirements today cannot be easily altered.

TRUTH: Scientific laboratories and their mechanical systems are specifically designed to handle changes in laboratory airflow volumes and pressures. Many modern systems can maintain a laboratory’s ventilation automatically, other - older – systems are controlled by a buildings’ facility management control computer.

FABRICATION: In laboratory design, the ventilation requirements for both supply and exhaust are calculated for pressure, air change rates and removal of heat load. If the Axiom’s installation is changed, all of these requirements would have to be recalculated and physically changed.

TRUTH: The balance of a scientific laboratory is based on pressure, air change rates and removal of heat load in accordance with ASHRAE requirements. However, the magnitude of volume being moved by a laboratory is such that the addition or subtraction of an Axiom to/from the lab’s mechanical system is insignificant in many labs.

Even simple VAV systems can automatically adjust for this change based on programmable pressures, and even simpler versions are controlled using a PC interface program.

BENEFITS: The Axiom’s flexibility is made possible by its design and that of existing laboratory ventilation infrastructure. This flexibility makes it possible for a laboratory to save over 50% of operational costs compared to Type B BSCs (over $50,000 compared to the life time operating costs of each Type B2 BSC).

Moreover, it allows facility and laboratory management to maximize the usefulness of their existing laboratory space, eliminating the need to operate both Type A and B BSCs for varying or alternating uses. One Axiom does the job of both Type A and B while costing the institution only the price of a single BSC.

The Axiom can be tied into almost any existing appropriate building exhaust system (with sufficient CFM reserve). Unlike Type B BSCs, no costly dedicated remote blower and ductwork are required.

ADVANTAGE: AXIOM

What is the exhaust connection used on the Axiom?

The Axiom, when installed in B-mode, is connected through a modified exhaust connection – a hybrid between a thimble (‘canopy’) and hard connection – that uses an inlet relief valve as a shock absorber to maintain balance with the buildings remote exhaust system. The inlet relief valve is used to ensure that the exhaust transition plenum is kept under negative pressure in B-mode – maintaining containment of hazardous chemistry in the duct.

MYTH: The inlet relief valve opens in the event that the building exhaust system pulls too much air through the BSC.

TRUTH: Without the inlet relief valve, the coupling between BSC and exhaust would be a so called a ‘push-pull’ system. Such systems are difficult to balance due to systemic pressure fluctuations.

Air is not pulled through a Type C1 by the exhaust system, conversely the exhaust system on a Type B BSC is required to pull air through the BSC. The inlet relief valve is open all the time when the Axiom is operating with proper building exhaust in B-mode.

BENEFITS: Acting like a shock absorber, the inlet relief valve is an adaptive technology that balances and maintains negative pressure by allowing a small volume of room air to bleed into the transition plenum.

The inlet relief valve is part of the system that allows the Axiom to operate in either an A-mode or B-mode and makes it flexible enough to work on most building exhaust systems with sufficient CFM capacity in reserve.

ADVANTAGE: AXIOM

MYTH: The Axiom’s Active Protection Protocol positively pressurizes ductwork, pushing potential volatiles within the duct airflow into undesirable areas.

TRUTH: During building exhaust failures, both Class II Type A and Type C BSCs positively pressurize ductwork.

A Type A BSC will do so for an unlimited time, until the BSC is turned off or loses power. What’s more, positive relief valves shunt chemically contaminated air back into the laboratory. Meanwhile, the BSC continues to operate as well, allowing operators to continue their work without forcing a shutdown.

A Type B BSC will not positively pressurize its ductwork. During a remote exhaust failure, Type B BSC must detect an exhaust remote failure within 15 seconds. During this time the cabinet is pressurized and the user is in the path of air from the work area back into the laboratory, characterized as “puff-back” – as defined by NIH/CDC in the BMBL 5th edition

A Type C BSC, such as the Axiom, prevents this positive pressurization from lasting longer than 300 seconds (or 5 minutes); limiting exposure to hazardous chemical vapors.

MISINFORMATION: Per AIHA/ANSI Z9.5-2012, section 5.4.3.5, Laboratory Ventilation. “Pressurizing contaminated ducts is not a recommended practice.”

TRUTH: ANSI Z9.5, Section 5.4.3.5 does not make this statement regarding positively pressurizing ductwork. ANSI Z9.5 for Laboratory Ventilation only briefly mentions Class II BSCs in the ventilation (section 5) and merely describes the types of connections and requirements for manifolding (ganging) BSCs with hoods and general exhaust.

From ANSI/AIHA Z9.5-2012, Appendix 4. Audit Form “Systems and ductwork are designed to maintain negative pressure within all portions of the ductwork inside the building when the system is in operation.”

BENEFITS: Existing Standards and equipment manufacturers all agree, positively pressurizing chemically contaminated ductwork under normal operation is not recommended.

The Active Protection Protocol that positively pressurizes duct work is an emergency response mode – not an operational mode. It does provide containment for a programmable period, not to exceed 5 minutes. During which the Type C1 Axiom provides an audible alarm, visual alarm – describing the alarm occurrence, and provides a countdown timer to BSC shutdown.

On many VAV mechanical systems, ganged exhaust pipes run to a central large volume plenum. These large VAV mechanical systems are significant enough in volume to absorb the volume of air being moved by an Axiom with the Active Protection Protocol engaged.

If a facility wishes to not have their ductwork positively pressurized, then the program can be set to operate for zero seconds.

Regardless of building exhaust system failure or normal BSC shutdown, the Axiom’s exhaust blower always runs for 10 seconds longer than the supply fan – eliminating any risk of pressurizing the BSCs interior, forcing air into the laboratory. 

The Axiom meets all requirements under ANSI Z9.5, NFPA 45, and NSF/ANSI 49 under normal operation. It also maintains an extended safety period during a critical building system failure.

<![CDATA[Use 98% less water, 85% less time cleaning pipettes]]>http://www.labconco.com/news/new-scrubair-pipette-washer-dryer Water conservation and lab efficiency have become topics of interest in modern lab design. In keeping up with current market needs, Labconco researched laboratory water usage and time-intensive manual processes and discovered one major sinkhole: Glass Pipette Washing.

Gallons upon gallons of tap water are poured down the drain as the common, siphon-style pipette washers fill then drain repeatedly. When washing is complete, rinsing generally begins using deionized (DI) water – a much more expensive solvent. After this time-consuming process of washing and rinsing, pipettes must be carefully removed, sorted into drying baskets and placed in an oven overnight.

Traditional Method

Total elapsed time to wash and dry a single load of pipettes: more than 23 hours.

Tapping into our experience with the design and manufacture of laboratory glassware washers, we decided to address this issue. Combining direct injection cleaning, the scrubbing action of percolation and the consistency of automation, we streamlined the washing process while requiring considerably less water and substantially less time.

Enter the ScrubAir Pipette Washer/Dryer, a one-of-a-kind automated unit to wash and dry in one place! The durable, steel-constructed unit can wash, rinse and dry up to 60 pipettes with just the touch of a button. One stop wash and dry eliminates extra handling steps, lowering the risk of glassware breakage and worker injury. Pipettes only need to be handled two times: once to load and once to unload.

The ScrubAir reduces water usage to as little as 12.5L for wash and rinse versus the 600L (at 2L/min) easily required for four hours of manual washing. At completion of the wash and rinse, forced-air drying is initiated through direct injection.

ScrubAir Method

Total elapsed time to wash and dry a load of pipettes with the ScrubAir: just under 5 hours.

This drops to 3.25 hours with the heated model. The user-friendly interface has three flexible and lockable program cycles including options for both wash and dry duration and number of rinse cycles. The standard model is equipped with a single water inlet and pressurized air inlet. The heated model has an additional water inlet built in, giving the user the added ability to rinse with purified water.

A previously labor-intensive, time-consuming and overall environmentally un-friendly process has been transformed into a fast, simple, environmentally friendly one. Users no longer need to babysit their pipettes. Press a button, walk away and let the ScrubAir do the work!

Find the right ScrubAir for your lab
