In the laboratory, vacuum conditions are required for experiments such as distillation, evaporation, crystallization, drying, sublimation, filtration, decompression, and degassing. Then, a multi-purpose vacuum pump and a diaphragm vacuum pump can provide vacuum conditions for the experiment. The degree of vacuum is different, so when you choose a vacuum pump, you need to know how much vacuum is required. Different vacuum pumps provide different vacuum conditions.

 

With the development of vacuum applications, many types of vacuum pumps have been developed. According to its working principle, it can be basically divided into two types, namely gas transfer pump and gas capture pump. With the application of vacuum application technology in the production and scientific research field, the requirements for its pressure range are becoming wider and wider, and most of them require a vacuum pumping system composed of several types of vacuum pumps to co-extract to meet the requirements of production and scientific research processes. The range of working pressures involved in the vacuum application department is very wide. Therefore, any type of vacuum pump cannot be completely suitable for all working pressure ranges. Only different types of vacuum pumps can be used according to different working pressure ranges and different working requirements. Vacuum pump.

 

When selecting laboratory equipment, whether it is evaporation, distillation, crystallization, drying, sublimation, filtration, decompression or degassing, a vacuum pump is required to provide vacuum conditions for it. According to different requirements, the degree of vacuum is different, and the laboratory equipment required is also different. Provide vacuum conditions for the chemical laboratory, and can provide circulating cooling water to the reaction device. The water added to the water tank can be used repeatedly, which overcomes the phenomenon of a large amount of wasted water when the tap water is directly flushed to obtain a vacuum.

Circulating water vacuum pumps can be used in glass reactor, short path distillation, rotary evaporator, molecular distillation, and other equipment.
