Reliable Performance Year After Year

KNF LABOPORT® Series Laboratory Vacuum Pumps

The KNF LABOPORT® series of diaphragm vacuum pumps are perfectly suited for laboratory bench applications. LABOPORT diaphragm lab vacuum pumps are oil-free, easy to use, and conveniently carried to wherever vacuum is needed. Manufactured in the USA with chemically-resistant PTFE heads, FFKM valves, and PTFE-bonded diaphragms -- LABOPORT vacuum pumps are built to last, delivering accurate, reliable performance year after year!

Quiet and compact, LABOPORT pumps offer flow capacity to 110 L/min, and end vacuum to 1.5 Torr. Additionally, LABOPORT vacuum pumps are designed to tolerate occasional liquids drawn into the pump system without damage, making them ideal for a wide range of laboratory applications including: rotary evaporation, filtration, vacuum ovens, and more.

In addition to the full line of LABOPORT vacuum pumps, KNF also offers an exclusive PowerDry® system -- available for chemical resistant vacuum pumps for moist gases. This unique feature automatically injects a burst of ambient air into the pump heads, clearing any trapped liquids. Benefits provided by PowerDry® -enabled LABOPORT vacuum pumps include: increased effective suction speed, and extended pump service life in wet gas application conditions.
