Beschreibung
Rotary evaporator flask, 25 ml, socket NS 14,5/23 is a pear-shaped, centred laboratory vessel intended for efficient solvent removal and concentration on rotary evaporators. Constructed from borosilicate glass 3.3, the flask offers superior resistance to chemical attack and thermal stress, supporting safe handling of diverse organic and aqueous media. Its centred pear shape facilitates continuous film formation and effective heat transfer throughout the rotation cycle, while the precision NS 14,5/23 ground joint provides a leak-free, vacuum-compatible interface with standard evaporator systems. Nominal volume is 25 ml and net weight is 0,025 kg, making the vessel practical for medium-scale sample processing in synthetic chemistry, natural-product isolation and pharmaceutical development. This glassware from manufacturer Rettberg is readily incorporated into existing rotary evaporation platforms for concentration, drying and solvent-recovery operations. Delivered as a single piece, the flask delivers consistent joint performance and mechanical reliability required for everyday laboratory evaporation workflows.
This article is part of Rotary evaporators, in Pumps, vacuum & evaporation.

Questions about Rotary evaporator flask, 25 ml, socket size 14,5/23, pear-shaped,
What is this article?
Rotary evaporator flask, 25 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 Präzisionsinstrumente.
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.
