Freeze drying systems, FreeZone®

Supplier: Labconco

Designed to handle the lyophilisation needs of research laboratories. Collectors that reach −50 °C are available with capacities from 1 to 18 litres. Cascade systems in 2,5, 4,5, 6 and 12 litre collector capacities that reach −84 °C are ideal for freeze drying samples with low eutectic temperatures. The FreeZone®  −105 °C bench top freeze dryer systems are suitable for samples with very low eutectic points including ones containing small amounts of methanol or ethanol.

  • Automatic start-up; pressing one button initiates collector refrigeration and vacuum
  • LCD screen for easy to read digital readouts of vacuum, temperature and service information
  • RS232 port (on all models except FreeZone® 1 litre systems) simplifies connection to a personal computer
Lighted graphs (on all models except FreeZone® 1 litre systems) display amber then green, to indicate when temperature and vacuum levels are right for adding samples. The 2,5, 4,5 and 6 litre freeze dry systems feature an automated valve for pressure regulation to help accelerate sublimation. The audible/visual alarm alerts the user to abnormal system events. Alarm messages are displayed on the LCD.

The upright collector chamber makes defrosting easy. All models may be manually defrosted by pouring water into the upright chamber to melt the collected ice. A collector drain hose allows convenient emptying of the melted ice. Larger systems feature hot gas defrost. Moisture sensor (on all models except FreeZone® 1 litre systems) protects the vacuum pump by preventing refrigeration or vacuum start-up when moisture is detected in the collector chamber. Vacuum break valve (on all models except the FreeZone® 1 litre systems) protects the system from oil backstreaming during power outages.

Ordering information: Other models, including versions with PTFE coated collectors, and a wide range of accessories including shelves and heated shelves are available, please contact VWR for more information.

Delivery information: Supplied with 3/4" ID vacuum hose and two clamps but without pump and accessories.
