Beschreibung
Vacuum seal VS-22 is a dedicated sealing component designed for Büchi rotary evaporator systems, ensuring reliable vacuum integrity during evaporation and distillation processes. This accessory belongs to the category of seals used in laboratory evaporation equipment and helps maintain the required low-pressure environment for efficient solvent removal and sample concentration. With a net weight of only 0,008 kg, the compact VS-22 seal is straightforward to install or replace within compatible Büchi assemblies. It supports consistent system performance in chemical, pharmaceutical and research laboratories where stable vacuum conditions are critical. Originating from Switzerland and offered by manufacturer Rettberg, the vacuum seal contributes to leak-free operation and prolongs the service life of evaporator glassware and connections. Supplied as a single piece, it serves as an essential spare or maintenance part for evaporation setups. Laboratories rely on such seals to minimise downtime and uphold process reliability during routine analytical and preparative work involving rotary evaporators.

Questions about Vacuum seal VS-22, for Büchi
What is this article?
Vacuum seal VS-22, for Büchi is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Präzisionsinstrumente.
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.
