KNF Laboratory Applications

We know what matters. At KNF, our focus is on developing intuitive solutions to the everyday challenges of laboratory work. We provide easy-to-use devices with a compact design and smart functions that make all the difference, ensuring low noise, high performance, and absolute reliability.

Select Your Application

KNF offers intelligent and compact pumps and systems for various laboratory applications.

Centrifugal Concentration

KNF centrifugal vacuum concentrators use a combination of centrifugal force, vacuum, and heat to rapidly and gently evaporate multiple small samples to either a dry or a wet pellet state.

Degassing & Desiccation

Degassing separates dissolved gases from liquids, which is critical in applications where gases can affect the final result. Desiccation, however, removes moisture from solids or maintains a dry environment for moisture-sensitive materials.

Rotary Evaporation & Distillation

Rotary evaporation and distillation are methods of liquid separation and purification achieved by heating a liquid to the point of vaporization and then collecting the vapour as condensate.

Fluid Aspiration

KNF diaphragm vacuum pumps offer an environmentally friendly, cost-effective alternative to water aspirators, with reliable low pressure and precise regulation.

Filtration

The  KNF LABOPORT® Filtration series pumps are compact, quiet, reliable, and maintenance-free — ideal for flask filtration, vacuum blotting, or vacuum manifolds.

Gel Drying

KNF’s robust vacuum pump solutions generate minimal noise and deliver outstanding results thanks to their chemical resistance and continuously adjustable vacuum. 

Liquid Dosing & Metering

KNF’s reliable dosing pumps with intuitive programmable controls allow precise, safe, and clean handling of neutral and corrosive liquids.

Liquid Transfer

KNF’s diaphragm liquid pumps are designed to be chemically resistant, making it possible to safely transfer neutral and aggressive liquids.

SPE — Solid-Phase Extraction

KNF offers a complete line of robust two-stage pumps with precise vacuum regulation for preparing samples via solid-phase extraction (SPE).

Vacuum Oven

Quiet and robust with a powerful vacuum — KNF LABOPORT® vacuum pumps are ideal for use with all brands of vacuum ovens and filtration devices.
