Beschrijving
Receiving flask, 3000 ml, round, with KSS 35, coated is a laboratory vessel for rotary evaporators, made from borosilicate glass 3.3 and fitted with a spherical ground joint socket KS 35/20. The round flask is finished with a plastic coating that serves as splinter and implosion protection during vacuum operation, helping to retain fragments should the glass fail under reduced pressure. With a nominal volume of 3 l and a net weight of 0,740 kg, this larger receiving flask is appropriate for higher-volume distillations, solvent recovery and condensate collection. Borosilicate glass 3.3 supplies the chemical resistance and thermal stability needed for routine laboratory evaporation tasks, while the KS 35 joint provides a secure interface to compatible rotary evaporator setups. Offered as a single piece from manufacturer Rettberg, the coated design supports safer handling in chemistry, pharmaceutical and research environments that depend on vacuum-rated glassware. The round geometry assists drainage and cleaning between runs, giving laboratories a robust, high-capacity receiving option with an integrated protective layer for demanding rotary evaporation workflows.
This article belongs on Vacuum & pump accessories, in Pumps, vacuum & evaporation.

Questions about Collecting flask, 3000 ml, round, spherical socket size 35, coated
What is this article?
Collecting flask, 3000 ml, round, spherical socket size 35, coated is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Vacuum & pump accessories, inside Pumps, vacuum & evaporation, in Instrumenten.
Vacuum accessories are the traps, the gauges, the hoses and the controllers between a pump and a flask. A cold trap is what keeps solvent out of the pump. A gauge is how you know the vacuum is the one the method asked for, rather than a hope.
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.
