FreeZone 4.5 Liter Benchtop Freeze Dryers are designed for lyophilizing light to moderate sample loads. The compact design is ideal for labs with limited floor space.

The upright stainless steel collector coil holds 4.5 liters of ice before defrosting. Two 1/3 hp HCFC/CFC-free refrigeration systems cool the collector to -84° C (-119° F), suitable for low eutectic point samples including acetonitrile.

Lyo-Works™ OS provides a real time display of collector temperature, vacuum level and optional End-Zone™ end point detection system, shown on a 5" full color, capacitive touch screen. Models with PTFE-coated collectors that can withstand corrosive compounds are available.

Vacuum pump, drying accessory and freeze dry glassware (if not bulk freeze drying) are required (not included).

  • Gail's Story Changed the Way We Think About Lab Freeze Drying

    Gail was responsible for something irreplaceable: a key link to the future of her company... and a cure. 
    When she visited Kelly at Labconco, Gail's struggle led to an epiphany that would change how laboratory freeze drying is done. With the creation of Lyo-Works OS, samples can now be monitored from anywhere. And with End-Zone™ End Point Detection, now FreeZone Freeze Dryers can even send you an alert when your samples are completely lyophilized.
