The KNF LABOPORT series of oil-free diaphragm vacuum pumps offer exceptional reliability and performance for a wide range of laboratory applications. These easy-to-use, compact, and quiet pumps are a welcome addition to any lab. Their patented multiport valves tolerate occasional wet vapors and droplets without damage or loss of performance. With a durable, maintenance-free design, LABOPORT pumps provide extended, trouble free performance for busy labs and academic settings.
Always check chemical compatibility for the chemicals that come into contact with your pump.
LABOPORT Vacuum Pump Testimonial

My team and I are responsible for studying plant physiology at different levels of total pressure for future greenhouse design and implementation in outer space. KNF LABOPORT® pumps are able to provide and maintain acceptable vacuum or atmospheres of different composition precisely for long periods, a necessity in our research. Both portable and easy to operate; KNF pumps are convenient to use by our undergraduate researchers.

Our research is conducted within the Presidential Initiative for New Vision for Space Exploration, which calls for mans return to the Moon, to go to Mars and then to worlds beyond. In this respect, KNF LABOPORT® pumps are very important technical and engineering components of our laboratory system.
