Freeze dryer

freeze dryer

Model: GZL-10


The freeze dryer is mainly used to storage the products that are easy to dehydrated, after filled with water, the product can recover to the initial status, no effect of biological activity; reach to dry status under very low temperature, the protein keeps waterless, but other main chemical bond keeps constant quality. The freeze drying is the best way to storage the biological tissue.


Germ, virus, plasma, serum, antibody, vaccine, vegetables, snake venom, flowers, fruit, dendrobe, worm grass, health care products, drug, microorganism, yeast, Plant Extract etc.

Main features

Danfoss compressor for refrigeration

Cold trap large opening, no inner disc, with sample pre-cool function, no need low temperature refrigerator

7 inch true color LCD control system, easy to operate, powerful function, English operation menu, indicating working status by graph and digital, indicate working time, condenser temperature, sample temperature, vacuum degree, also record the dry curve.

Embedded industry system, ARM9 core control circuit, 32M RAM 128M flash, fast response, mass storage capacity, equipped with USB communication port

Control system automatically save the test data, and can be reviewed by real time graph and historical graph

The drying chamber is made by one time injection moulding process of transparent PC material, corrosion resistant, breakage proof, no adjesion, good leakproofness, easy to observe the whole working process.

Vacuum pump and main machine are connected with international standard KF quick coupling, easy but reliable.
