Description
Receiving flask (35/20), 1000 ml, is a glass collection vessel for rotary evaporation setups. It is intended for the rotary evaporators REVA-180-001 and REVB-180-001, where condensed distillate must be gathered safely during solvent recovery and sample concentration. The 35/20 joint defines the connection geometry to the compatible glass path, while the 1000 ml capacity supports preparative and routine laboratory volumes without frequent emptying. Net weight is 0,25 kg and the flask is supplied as a single piece in the LBX INSTRUMENTS range from manufacturer Labbox. Analytical, synthesis and quality-control laboratories use receiving flasks of this type when working with organic solvents, extracts or process streams that leave the condenser as liquid distillate. Pairing a correctly jointed 1000 ml receiver with the matching evaporator platform helps maintain a closed vapour path and reduces the need for improvised adapters. The flask is positioned as a dedicated spare or replacement component for REVA and REVB series instruments rather than a universal multi-joint vessel. Clear joint and volume markings in the product identity make selection straightforward when stocking accessories for continuous rotary-evaporation workflows.

Questions about Receiving flask (35/20), 1000 ml
What is this article?
Receiving flask (35/20), 1000 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Vacuum & pump accessories, inside Pumps, vacuum & evaporation, in Lab instruments.
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.
