Description
MD 4S NT is a three-stage diaphragm pump for laboratory vacuum applications, supplied without a power cable to allow free choice of mains connection. It features NRTL certification (C/US) and multi-range voltage compatibility covering 200-230 V/50-60 Hz, 100-115 V/50-60 Hz and 120 V/60 Hz. The membrane-pump design from manufacturer VACUUBRAND enables clean vacuum generation for filtration, evaporation support and general laboratory process work. Net weight is 16,800 kg and gross weight 19,100 kg, underscoring a durable build for everyday laboratory service. Originating from Germany and packed as a single unit, the MD 4S NT is intended for facilities that require a certified three-stage diaphragm pump without a pre-fitted power cord. Its broad electrical acceptance and NRTL listing simplify integration into regulated laboratory infrastructures where reliable, oil-free vacuum performance and flexible cabling are essential for continuous operation.

Questions about MD 4S NT, without mains cable
What is this article?
MD 4S NT, without mains cable is the article on this page. Luminix Health distributes Vacuubrand 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.
