Beschrijving
Rotary evaporator flask, 5 ml, socket NS 14,5/23 is a pear-shaped, centred laboratory vessel engineered for efficient solvent removal and sample concentration on rotary evaporators. Fabricated from durable borosilicate glass 3.3, the flask combines high chemical resistance with excellent thermal shock tolerance, making it suitable for a wide range of organic solvents and aqueous media. The centred pear geometry promotes uniform film formation and improved heat transfer during rotation, while the precision NS 14,5/23 ground joint guarantees a reliable, vacuum-tight seal with standard evaporator assemblies. Nominal volume is 5 ml and net weight is only 0,012 kg, allowing convenient handling of small-scale samples in synthesis, analytical preparation and method development. This glassware from manufacturer Rettberg integrates seamlessly into existing rotary evaporation workflows for concentration, drying and solvent recovery tasks. Supplied as a single piece, the flask supports reproducible laboratory practice where consistent joint fit and robust construction are essential for daily use in research and quality-control environments.
This article is part of Rotary evaporators, in Pumps, vacuum & evaporation.

Questions about Rotary evaporator flask, 5 ml, socket size 14,5/23, pear-shaped,
What is this article?
Rotary evaporator flask, 5 ml, socket size 14,5/23, pear-shaped, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Rotary evaporators, inside Pumps, vacuum & evaporation, in Instrumenten.
A rotary evaporator spins a flask under vacuum so solvent boils off a sample at a modest temperature. The flask size, the condenser type and the vacuum the seal can hold are the specification. Bumping is a flask that was too full or a vacuum that arrived too fast.
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.
