Chemglass Recovery Flask 50 ml Heavy Wall 24/40 Outer Joint - Lot of 5 Flasks

The Chemglass (Part Number CG-1512-01) Recovery Flask is a specialized borosilicate glass vessel designed primarily for use with rotary evaporators. Unlike standard round-bottom flasks, this "recovery" style features a distinct pear-shaped (or teardrop) geometry. This tapered lower section is critical for maximizing sample retrieval; it allows small volumes of liquid to pool in the bottom "cone," making it significantly easier to recover valuable concentrated products via a pipette or syringe once the solvent has been evaporated.

Capacity-wise, this specific flask holds 50 mL and is equipped with a standard 24/40 Outer Ground Glass Joint. The "Outer" (Female) joint configuration allows it to slip directly over the standard "Inner" (Male) vapor tube of most rotary evaporators or bump traps. A defining feature of the CG-1512 series is its Heavy Wall construction. Because rotary evaporation involves subjecting the glassware to high vacuum levels, standard thin-walled flasks risk implosion. The thicker glass walls of this model provide the necessary structural integrity to withstand deep vacuum cycles safely.
