Characteristics of uses:

Providing vacuum condition for the processes of evaporation, distillation, crystallization, drying, sublimation, filtration and decompression and degassing. And extracting for various materials with severe toxicity, flammability and probability of explosion, strong acid and alkali. Besides applicable occasion of circulating water vacuum pump and spiral slice vacuum pump, it also can be used in fields like product analysis of medical treatment and medication and Police detective techniques. 

1.Replace circulating water vacuum pump and spiral slice vacuum pump.

2.No need of any working medium. No friction in working parts.

3.The vacuum is stable. And the degree is easy to be controlled and can be adjusted according to experiment requirements.

4.All parts that exposed to gas need surface treatment with Teflon(PTFE), has complete chemical resistant ability.

5.Valve plate adopts imported materials.

6.The special machine is made by the famous electric manufacture ODM with reasonable transmission design and self cooling exhaustion system that can work for a long time.

7.Small volume, light weight, easy to move and save space in the lab.

8.Easy to repair and maintain.
