Laboratory Pumps for Air, Gases and Vapours

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

KNF LABOPORT chemically-resistant diaphragm vacuum pumps for aggressive media. These pumps transfer and evacuate almost all laboratory gases and vapors. Special features include resistant materials such as solid PTFE for the pump head, FFPM for the valves, and KNF textured diaphragm with PTFE-coated closed surfaces. These pumps are virtually gas-tight; media remains uncontaminated.

KNF LABOPORT chemically-resistant diaphragm vacuum pumps with KNF self-drying system. These pumps offer all the advantages of chemically-resistant vacuum pumps plus a built-in automatic self-drying system for applications with wet gases, such as vacuum drying chambers. Condensate is blown out of the pump heads (at regular intervals set by the user) while the vacuum is maintained in the chamber. Regular drying of pump heads shortens pump downtime and increases the pump's service life.

KNF LABOPORT chemically-resistant vacuum systems for various process applications in laboratories. These vacuum systems are built around chemically-resistant LABOPORT diaphragm vacuum pumps. With pump, modular accessories and base plate, a custom system can be built as needed - easily and without special tools. A range of chemically-resistant vacuum pumps is available.

KNF LABOXACT chemically-resistant vacuum systems for gentle distillation. This 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 fully automatic vacuum system for up to ten users. All components of the base station are mounted compactly on a single base plate. Various types of vacuum supply points with non-return valves are available. These can be easily integrated into existing laboratory equipment or into new setups. A mobile controller unit is available for controlled vacuum supply.
