FreeZone 4.5L -84C Freeze Dryer_Lyophilizer for moderate sample lyophilizing

FreeZone 4.5 Liter -84C Benchtop Freeze Dryers

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 touchscreen. 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).
