The KNF LABOPORT corrosion-resistant vacuum pumps from KNF Neuberger are compact diaphragm pumps that feature polytetrafluoroethylene (PTFE)-wetted parts, condensate-resistant multi-port FFPM valves, and PTFE-bonded diaphragms. The pumps use no pump oil, operate without maintenance or water requirements, and perform quietly, even when continuously running corrosive solvent vapors.
The portable pumps offer alternatives to oil-lubricated pumps, water aspirators, piston pumps, and house vacuum. They can handle most aggressive vapors and can tolerate occasional condensate and other abuse typically encountered in busy laboratories without damage. The pumps quickly connect without tools to system using a vacuum hose. The pumps can achieve flow rates to 60 L/min and generate vacuum to 1.5 Torr (29.9 in Hg).
