Single-Neck Round-Bottom Boiling Flask (CS-F30) 5 ml–2000 ml

The CS-F30 Single-Neck Round-Bottom Boiling Flask is a laboratory-grade reaction vessel designed for heating, reflux, distillation, and chemical synthesis. Manufactured from high-quality borosilicate glass, each flask is hand-blown from glass tubing to ensure uniform wall thickness and enhanced mechanical strength.

Its round-bottom geometry promotes even heat distribution when used with heating mantles or oil baths, while the standard taper outer joint allows seamless connection to condensers, adapters, and other laboratory glassware.

Available in capacities from 5 ml to 2000 ml, with larger sizes available on request.
