-56°C Benchtop Mini Freeze Dryer, LCD Display

-56°C benchtop mini freeze dryer consists of four parts, vacuum system, heating/cooling system, refrigeration system and electrical instrument control system. Each part plays its role in the freeze drying process, and is of equal importance for the operation of the machine.


-56°C benchtop mini freeze dryer indicates that the condensation temperature is below -56 degrees centigrade. This is a lab scale freeze dryer, due to its fair price and compact design, and is mostly used in lab tests. The mentioned above systems make up the -56°C small freeze dry machine, and more detailed components should be a vacuum pump, heating/cooling device, refrigeration unit, control panel, condenser, and drying room.

Features of Hawach’s -56°C benchtop mini freeze dryer

15. The benchtop mini freeze dryer can be upgraded to -80°C laboratory lyophilizer with dual condensers.

Applications of Hawach’s -56°C benchtop mini freeze dryer

1. Freeze drying is carried out at low temperatures, so the benchtop mini freeze dryer is particularly suitable for many heat-sensitive substances such as proteins and microorganisms, widely used in medicine.
2. When drying at low temperatures, some volatile components in the substance lose little, which is suitable for drying some chemical products, medicines, and foods.
3. Since the drying is carried out under a vacuum, there is very little oxygen, so some easily oxidized substances are protected.
