Model: RTFD-12E
General Introduction: Model RTFD-12E is suitable for freeze-drying experiment in laboratory. This equipment is used for long term preservation for bacteria, fungi and other microbial strains. After freeze drying process, samples can be sealed in the ampules.
Freeze Drying Theory:  Freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After freeze drying process, a long term preservation for material is much easier. They can be restored to original state and maintain their chemical and biological characteristics after being watered. The vacuum freeze drying technology, which is also called sublimation drying, is a technical method that freezes the samples in advance, and then sublimates its moisture under vacuum state.
