Diaphragm pump

The diaphragm pump (also called diaphragm), is a type of vacuum pump widely used in the laboratory
In the laboratory, diaphragm pumps are the first choice for their chemical resistance, the absence of oil residues and the possibility of recovering solvents. To learn more: https://en.wikipedia.org/wiki/Diaphragm_pump.
