Application: It is suitable for freeze-drying of bacteria, virus plasma, serum, antibodies, vaccines, drugs, microorganisms, yeast, cosmetics, health products, Chinese herbs, chemicals and plant extracts for biological research.

Application principle: Vacuum freeze-drying is a technology that uses the principle of sublimation to dry. It is a process in which the dried substance is quickly frozen at a low temperature, and then the frozen water molecules are sublimed directly into water vapor escape under the adapted vacuum environment. The product obtained by freeze-drying is called Iyophilizer. This process is called Iyophilization. The substance is always in a low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the substance. The sublimation process will not be concentrated due to dehydration, avoiding the side effects such as foam and oxidation produced by water vapor. The dry substance is a dry sponge and porous, the volume is basically unchanged, and it is easily dissolved in water and restored to its original state. To prevent the physical and biological degeneration of dry substances to the greatest extent.
