Description
Vacuum pump 2561 delivers a free-air displacement of 57 l/min and reaches an ultimate vacuum of 6,7 mbar, making it suitable for general laboratory vacuum tasks such as filtration, degassing, drying and rotary evaporation support. The unit operates on 230 V at 50/60 Hz single-phase supply and is supplied with both Schuko and UK plug leads for flexible installation in European and UK laboratory environments. With a net weight of 7,5 kg, the pump remains compact enough for benchtop placement while providing stable continuous duty performance. This WELCH vacuum pump model 2561 is designed for reliable everyday use in chemical, pharmaceutical and life-science laboratories where moderate vacuum levels and consistent flow are required. The dual-plug configuration simplifies cross-site deployment without additional adapters. Packaged as one complete pump unit, it is ready for immediate connection to vacuum lines, manifolds or apparatus requiring oil-free or low-maintenance vacuum generation within the stated performance envelope.
This article is part of Vacuum pumps, in Pumps, vacuum & evaporation.

Questions about Vacuum pump 2561, 57l/min, 6.7mbar, 230V 50/60Hz, 1 Ph with Schuko and UK plug l
What is this article?
Vacuum pump 2561, 57l/min, 6.7mbar, 230V 50/60Hz, 1 Ph with Schuko and UK plug l is the article on this page. Luminix Health distributes WELCH 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.
