Description
Vacuum pump oil for the CRVpro series is a dedicated lubricant supplied in a 1 l pack for CRVpro rotary vane vacuum pumps. The oil has a density (D) of 0,86 to 0,88 g/cm³, a flash point (flp) of 245 °C and a boiling point (bp) greater than 390 °C, defining the density and thermal profile stated for this grade. Available from manufacturer WELCH Vacuum for the CRVpro series, it is intended as the matching oil for filling, top-up, and oil-change work on those pumps. The unit quantity is 1 liter and the stated weight is 1,1 kg, which suits bench-side maintenance and storage beside the pump. Laboratories running CRVpro packages that include an oil change set can use this oil as the corresponding refill. Selecting the series-specified vacuum pump oil supports lubrication and sealing within the operating context of CRVpro rotary vane pumps whenever fresh oil is required during routine service or commissioning.
This article is part of Vacuum pumps, in Pumps, vacuum & evaporation.

Questions about Vacuum pump oil, for CRVpro series, 1 l
What is this article?
Vacuum pump oil, for CRVpro series, 1 l is the article on this page. Luminix Health distributes WELCH Vacuum 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.
