CHARACTERISTICS OF USES:

Providing vacuum condition for the processes of evaporation, distillation, crystallization, drying, sublimation, filtration and decompression and degassing. And solvent recollection, 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.Resistcorrosion.
5. The special machine can work for a long time.
6. Small volume, light weight, easy to move and save space in the lab.
7. Easy to repair and maintain.
8. Input flask can prevent solid particles and liquid water into pump.
9. Output condenser can realize second recovery of low boiling-point material to improve recovery efficiency to avoid waste gas of solvent into the atmosphere.
