Four sample valves increase capacity and flexibility—allow connection of flasks and other glassware, which can be lyophilized simultaneously. Automatic temperature control enhances consistency and convenience of repetitive protocols. Chamber prefreezes samples to save money and time, eliminating the need for a separate freezer and product transfer. Vacuum control/break valve maintains setpoint vacuum level to speed the process.


  • Microprocessor controls up to five different temperature programs, plus up to five ramping and holding segments
  • Sensor probe digitally monitors sample temperature
  • Hot gas defrost shuts off automatically when refrigerant reaches 60°C or after 3 hours; allows for easy cleanup of up to 1.8L of water/2.5L of ice
  • Two 1/3hp CFC-free and HCFC-free refrigeration systems cool the collector to -85°C (-121°F)
  • Built-in pneumatic stoppering mechanism on processing shelf does not require compressed gas
  • Shelf (12.4W × 14.5 in. D) accommodates glassware from 31 to 148mm Circulating fluid in processing shelf can be set to a pre-freeze temperature of -75°C (-103°F) or between -55° to +50°C (-67° to +122°F) with ±1°C stability
  • Refrigeration system and 1000w heater efficiently cool and heat processing shelf
