Description
The MD 4 NT is a three-stage diaphragm pump intended for laboratory vacuum applications, carrying NRTL certification (C/US) and configured for 230 V / 50-60 Hz supply with a UK/IN power cable. This membrane pump is delivered as a single-piece unit and forms part of the MD 4 NT series employed in research and analytical environments. The instrument from manufacturer VACUUBRAND originates in Germany and is supplied ready for connection through the included UK/IN mains cable. Net weight is 16.9 kg and gross weight is 19.7 kg, consistent with a durable laboratory construction for bench or system use. The three-stage diaphragm arrangement delivers the vacuum performance characteristic of this model, while the C/US NRTL marking documents the stated certification. Electrical rating remains 230 V / 50-60 Hz for the UK/IN cable variant. Facilities that need a certified three-stage diaphragm pump with UK/IN power connection obtain a clearly defined unit that matches the manufacturer specification for voltage, staging and regional cabling without additional claims.

Questions about MD 4 NT, UK/IN
What is this article?
MD 4 NT, UK/IN 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.
