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.
Freeze dryer RTFD-20FB stopper type , it is suitable for freeze-drying experiment in laboratory and small scale production. It is used for product in bulk and product in vial .
