The choice of a vacuum pump for the chemical laboratory depends more and more on economical and ecological qualifications. The water jet pump, widespread because of its simple and robust design, can satisfactorily fulfil these qualifications only in a few applications. Rotary vane and diaphragm vacuum pumps are of much more complicated design; the most outstanding assets, however, are that they work without contamination of water; further, they provide a large pumping speed also at low suction pressures.
