General Introduction : Â Freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After freeze drying process, Â 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
Model LGJ-12S standard type freeze dryer is used for experiment in laboratory.
It is suitable for product in bulk.It has heating shelves and programmable function.
