Product details

We supply benchtop freeze dryer Model RTFD-10D, it is suitable for freeze-drying experiment in laboratory, for product in bulk,in vials, and in flask. It is small and compact structure, condenser temp. -50℃ and -80℃ available, with 1 year Warranty. 


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.

2. Press and hold the inflation valve on the control panel and immediately turn off the vacuum pump;

3. When the pressure is displayed at atmospheric pressure, open the plexiglass cover and take out the sample;

4. Turn off the refrigerator, press and hold the total switch key for more than three seconds, and finally turn off the main power switch;

5. After the ice in the cold trap is completely turned into water, open the water outlet valve on the left side of the chassis to drain the water, clean the inner wall of the cold trap with a dry cloth, and cover the large filter paper to prevent dust.
