KNF LABOPORT^® is the name of our chemically resistant diaphragm vacuum pump line for aggressive media. These pumps can be used to transfer and evacuate almost all laboratory gases and vapors. They are characterized in particular by the use of resistant materials such as all-round PTFE for the pump head, FFPM for the valves, and KNF's structured diaphragm with a PTFE coating.

KNF is proud to offer a complete line of laboratory pumps and systems for a variety of bench applications. KNF laboratory vacuum pumps provide strong flow, precise control and excellent solvent recovery.
