I.Characteristics of Uses:
Providing vacuum condition for the processes ofevaporation, 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
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 withTeflon(PTFE), has complete chemical resistant ability.
5.The special machinecan work for a long time.
6.Small volume, light weight, easy to move and save spacein the lab.
7.Easy to repair and maintain.
