Common problems of diaphragm vacuum pump principle
The use of chemical reaction instruments such as rotary evaporators, centrifugal concentrators and variety evaporators can not be separated from the function of vacuum pump. People usually choose the circulating water vacuum pump as the supporting product of rotary evaporators, but with the development of science and technology, the diaphragm vacuum pump used in laboratory has gradually replaced the circulating water vacuum pump and has been accepted by the majority of users.
Although the price of circulating water vacuum pump is affordable, it will encounter some problems in use, such as poor corrosion resistance of organic solvents, insufficient vacuum degree, slow distillation speed of DMSO, bad smell in laboratory, need to change water for cooling and so on. However, these problems are not problems for diaphragm vacuum pump used in laboratory.
