Description
Rocker 400 oil-free vacuum pump 120 V is a robust laboratory vacuum pump featuring a lubricant- and oil-free piston that requires no oil changes and minimal maintenance. Operating on AC 120 V, it achieves a maximum vacuum of −680 mmHg with a free-air displacement of 37 l/min at 1750 rpm and 1/6 HP. The pump is equipped with a ProteTM filter, thermal safety shutdown and CE certificate, plus a moisture trap and overflow protection for reliable daily use. Hose barb connection is 5/16 inch (8 mm). Compact housing measures 31,0 × 13,5 × 20,4 cm and weighs 5,2 kg. This new-model unit from manufacturer Witeg is intended for filtration manifolds, vacuum ovens, SPE workstations and general laboratory vacuum applications where clean, oil-free air and consistent performance are essential. The oil-free piston design eliminates contamination risk and reduces service intervals, supporting continuous operation in analytical, quality-control and research environments.

Questions about Rocker 400 oil free vacuum pump 120 V
What is this article?
Rocker 400 oil free vacuum pump 120 V is the article on this page. Luminix Health distributes Witeg 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.
