LABOPORT® Diaphragm Vacuum Pumps

Series N 816.3 pumps are double-headed, dry-running devices used in a wide range of laboratory applications. For instance, The N 816.3 KT.18 is well-suited for use in degassing, desiccation, solid phase extraction and so on.

The heart of these very compact pumps is a KNF structured diaphragm, stress-optimized using the finite element method (FEM). Effectively, this results in a very compact pump size and a longer service life of the diaphragm.

All .45 versions come with a fine control valve and a vacuum gauge.
