Description
Receiving flask 1000 ml round with KS 35 is a laboratory vessel for rotary evaporators, produced from borosilicate glass 3.3. This round flask features a ball joint socket KS 35/20 together with a plastic coating that serves as splinter and implosion protection under vacuum. With a nominal volume of 1 l and a net weight of 0,305 kg, it accommodates higher condensate loads in distillation and solvent-recovery procedures. The single-neck KS 35 design provides a secure interface to standard rotary evaporator systems used across research and preparative laboratories. Chemical resistance and thermal stability of borosilicate glass 3.3 are retained while the overcoat improves mechanical safety during reduced-pressure work. This coated receiving flask from manufacturer Rettberg supports efficient collection of condensed solvents and distillates. Round geometry facilitates emptying and handling of larger volumes. Supplied as one piece, it is intended for laboratory vessel use in rotary evaporation applications where capacity and operator protection are both required.
This article is part of Vacuum & pump accessories, in Pumps, vacuum & evaporation.

Questions about Collecting flask, 1000 ml, round, spherical socket size 35, coated
What is this article?
Collecting flask, 1000 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 Instruments de précision.
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.
