Diaphragm vacuum pumps represent one of several pump designs ideal for creating vacuum conditions in the laboratory. As they avoid the need for pump oil, diaphragm pumps offer much higher corrosion resistance and typically require much less service support than oil-sealed pumps. Operators working in lab environments often choose a diaphragm vacuum pump for applications in which chemical resistance is important. The ultimate vacuum of a diaphragm pump can reach as low as 0.3 Torr, which is sufficient to handle most suction and evaporative applications in the lab. Chemically resistant PTFE pump heads ensure long operating life, allowing these diaphragm pumps to serve corrosion-prone rotary evaporators, or flask and bottle evacuations, all without contaminated aspirator water.
