Description
MD 4C EX VARIO +AK+EK is a three-stage chemistry pump stand for vacuum work with potentially explosive atmospheres. The unit runs on 230 V / 50 Hz and carries full ATEX marking: pumping chamber II 2G Ex h IIC T3 Gb X, exterior without inert-gas purge II 3G Ex h IIB T4 Gc X, exterior with inert-gas purge II 2G Ex h IIB T4 Gb X, and motor II 2G Ex db IIB T4 Gb. Supplied complete with AK and EK modules from manufacturer VACUUBRAND, it includes a power cable without plug and a 4-20 mA control line without plug for variable-speed operation. Accessories required to drive ATEX Category 2 speed-variable pumps and ATEX vacuum sensors must be mounted outside the hazardous zone, preferably inside suitable control cabinets. Electrical installation in EX areas must follow applicable national rules and IEC EN DIN 60079-11 and be performed by a competent specialist. Net weight is 37,000 kg and gross weight 53,000 kg. The stand is intended for chemistry laboratories that need certified explosion protection when handling solvent vapours and other flammable process gases under controlled vacuum conditions.

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