Laboratory pumps for air, gases and vapors

Diaphragm vacuum pumps and compressors for air, gases and vapors. general-purpose pumps for various laboratory applications such as vacuum distillation, multiflask filtration, gel drying.

KNF LABOPORT, chemically-resistant diaphragm vacuum pumps  for aggressive media.  These pumps transfer and evacuate almost all laboratory gases and vapors. Their special feature is the resistant materials used such as full PTFE for the pump head, FFPM for the valves, and the KNF structured diaphragm with PTFE-coated, closed surfaces. Thus, the pumps are virtually gastight; the media remains uncontaminated. These pumps tolerate ingestion of occasional without damaging or degrading performance.

KNF LABOPORT, chemically-resistant diaphragm vacuum pumps with KNF self-drying system. They offer all of the advantages of the chemically-resistant vacuum pumps. In addition, an automatic self-drying system is built in for applications with wet gases, such as at vacuum drying chambers. The condensation is blown out of the pump heads, at regular intervals set by the user. The vacuum in the vacuum chamber is maintained. Regular drying of the pump heads shortens the pump-down time, increasing the pump's service life.

KNF LABOPORT, chemically-resistant vacuum systems for various process applications in laboratories. The vacuum system is based on the chemically-resistant LABOPORT-series diaphragm vacuum pumps. With each of these pumps and the modular accessories, a customized system can be built on the base plate - easily and without special tools. Various chemically-resistant vacuum pumps are available.

KNF LABOXACT, chemically-resistant vacuum systems for gentle distillation. The LABOXACT vacuum system was developed specifically for use with rotary evaporators. It allows reliable control of the evaporation process and a high rate of recovery, even with low-boiling-point solvents.

KNF LABOBASE, a fully-automatic vacuum system for up to ten users. All components of the base station are mounted compactly on one base plate. Various kinds of vacuum supply points with non-return valves are available. They can be easily integrated in existing laboratory equipment as well as in new designs. A mobile controller unit is available for controlled vacuum supply.

KNFLab TOWER, universal laboratory instrument for three types of applications: Aspiration, filtering, pipetting.  Simple handling and easy to use, mobile, fits under hoods and laboratory benches. Extremely quiet operation and useable with various types of pipettes and tips. Accurately adjustable pipetting rates.
