Product Description

 

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.

RTFD-18HB  top press type freeze dryer is used for freeze drying experiment in laboratory.
It is vertical freeze dryer, suitable for drying products in bulk and in vial. This machine has heating shelves and programmable function.
