Description
Diaphragm vacuum pump N 938.50.KT.18 is a laboratory vacuum unit designed for controlled evacuation tasks in research and analytical environments. The model designation N 938.50.KT.18 identifies this diaphragm pump configuration for integration into bench and instrument setups where oil-free vacuum generation is preferred. It is supplied as a complete unit in a single-piece pack, with a stated weight of 9,000 kg, making it suitable for fixed laboratory installation rather than frequent relocation. The pump comes from manufacturer KNF and is positioned for vacuum technology applications alongside compatible accessories and regulation components in the same product family. Laboratories use diaphragm vacuum pumps of this type for filtration support, sample concentration support and general vacuum supply where a dedicated laboratory-grade unit is required. Clear model labelling helps match the pump to existing LABOPORT®-related systems and spare parts. This offering provides a straightforward way to specify the N 938.50.KT.18 diaphragm vacuum pump for procurement and equipment inventories without additional performance claims beyond the stated identity and pack data.
This article is part of Vacuum pumps, in Pumps, vacuum & evaporation.

Questions about Diaphragm vacuum pump, N 938.50.KT.18, 1 unit(s)
What is this article?
Diaphragm vacuum pump, N 938.50.KT.18, 1 unit(s) is the article on this page. Luminix Health distributes KNF for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
