Questions about MD 4C EX VARIO, ATEX
What is this article?
MD 4C EX VARIO, ATEX 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.
