The vacuum freezing drying technology, which is also called sublimation drying,
is a technical method that freezes the samples in advance, and then sublimates
its moisture in the vacuum state. Materials are easier for long term preservation
after freezing drying processing.

They can be restored to the original state and maintain its chemical and biological characteristics after being watered. So the freezing drying technology is widely used
in medicine, pharmacy, food production, chemistry industry and biological products etc.

LGJ-50F Freeze Dryer with stopper

LGJ50F Freeze Dryer is suitable for a small amount production, freeze drying experiment
