LABOPORT® is the perfect vacuum pump for all types of rotary evaporators, gel drying systems, vacuum concentrators, vacuum drying ovens, filtration and applications in the laboratory like the degasification, manifold filtration, vacuum drying and others.

These pumps are maintenance free and oil free, and therefore there is no need for an oil change or draining of accumulated residual water. They are lightweight, portable and are equipped with a pump head of PTFE, which is resistant to strong chemicals and corrosive liquids. The valves from the KNF multi-port are highly resistant to possible damages caused by occasional condensing liquids, which originate occasionally without affecting the level of achieved vacuum.
This new generation of KNF Neuberger pumps are extremely silent, because of a recently patented technology of valves and which reduces the operating noise. These are the perfect replacement pumps of any older technology of vacuum pumps like rotary pumps in an oil a bath or the water aspirator pumps previously used in the laboratory. The LABOPORT pumps have a structural Teflon coated diaphragm, which is the reason why they are able to generate an excellent vacuum during their long lasting working lifetime. This series of pumps includes a number of different models with different pumping rates and different levels of final vacuum.
