Product Description

LGJ-12SA standard experimental electric-heating vacuum freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After the freeze drying process,a long term preservation is much easier. They can be restored to the original state and mantain their chemical and biological characteristics after being watered. It is a kind of the small vertical freeze-drying unit with shelf heating and programmable functions.

LGJ-12SA standard experimental electric-heating vacuum freeze dryer is suitable for experiment in laboratory and small amount production ,and it can meet the regular freeze dying requirements of the most laboratories.
