Shanghai Zhixin desktop freeze dryer zx-lgj-1

&Nbsp;
Bench type freeze dryer
Zx-lgj-1 type
Instrument selection:
Common methods for sample evaporation, drying, concentration and purification include:
■ distillation and rotary evaporation methods under high temperature and atmospheric pressure, but can only process a single sample

■ fast evaporation and nitrogen blowing method at low temperature, but few samples are processed and the operation is complex

■ evaporation under room temperature and vacuum, vacuum centrifugation and concentration method, with conditional requirements for samples

■ under low temperature and high vacuum conditions, the freeze dryer method can sublimate and keep the sample active, which takes a long time

Vacuum freeze dryer is widely used in medicine, pharmacy, biological research, chemical industry, food and other fields
The freeze-dried articles are easy to be stored for a long time
After water supply, they can return to the state before freeze-drying and maintain the original biochemical sustainability
