Class II, Type C1 Biosafety Cabinet: Versatility, Safety & Savings Comparison

Purifier Logic+ A2 Biosafety Cabinet


Comparisons of Class II, Type A, Type B and Type C biosafety cabinets discern gaps in laboratory cost, safety, energy conservation and versatility. These four facets have become parameters by which all laboratory equipment is weighed and measured. The following gap analysis highlights the strengths and limitations of traditional Class II Type A and B biosafety cabinets (BSC's) and differentiates the role of the Type C1 BSC. The Type C1 bridges the gap between the recirculating Type A's and the vented Type B's and brings along new safety features and energy savings.


Just when you thought you knew all aspects of the various types of Class II biosafety cabinets, along comes something truly innovative. Biosafety cabinets have experienced some general upgrades over recent years. Controls have become more interactive and energy-saving blowers have given us a reason to replace older cabinets. However, the core design of cabinet airflow has remained relatively unchanged.

However, Labconco introduced a new cabinet in 2014 that eases the selection process for Class II BSC's. The novel design drove industry experts to conclude that there are still new and enhanced ways to move air. Many industry experts agreed that this new cabinet fit neither the definition of a Type A, nor the definition of a Type B. Its unique airflow and design required it to have an entirely new classification – welcome the Class II, Type C1 biosafety cabinet (BSC).

This new Class II subtype's unique airflow configuration, installation, and exclusive ability to maintain safety even during emergency situations, compelled NSF International® to adopt, define and designate the new type of BSC in NSF/ANSI Standard 49. The product development team at Labconco Corporation describe the benefits of the Type C1 as, "unparalleled with conventional cabinets when summing up versatility, safety and savings. If you took the best features from A2s, B1s, B2s and put them all in a bowl with some new ideas and mixed them up you have the Type C1."
