Chemglass Heavy Wall Recovery Flask 100 ml 24/40 Outer Joint Lot of 4 Flasks

The Chemglass (Part Number CG-1512-03) Heavy Wall Recovery Flask is a specialized 100 mL borosilicate glass vessel engineered specifically for use with rotary evaporators. Unlike standard round-bottom flasks, this "recovery" style flask features a unique pear-shaped (or egg-shaped) geometry that facilitates the efficient retrieval of high-value solvents, viscous liquids, or solid precipitates. The tapered lower portion allows you to access the very bottom of the flask with a spatula or pipette, ensuring maximum sample recovery after evaporation.

Constructed from Type I Class A Borosilicate Glass, this flask is manufactured with heavy walls to withstand the mechanical stress of continuous rotation and the pressure differentials associated with high-vacuum applications. It is precision-balanced to prevent "run-out" or wobbling while spinning on the rotovap, which protects the vapor tube from stress fractures. The neck features a standard 24/40 Outer Joint that provides a secure, leak-tight connection to the main vapor tube of most standard rotary evaporation systems (e.g., Buchi, Heidolph, or IKA).

Used, in great condition.
