Single-Neck Flat-Bottom Flask – 500 ml

The MEIWLABY 500 ml Single-Neck Flat-Bottom Flask is a laboratory-grade reaction vessel designed for heating, mixing, reflux, and general chemical processing. Manufactured from high-quality borosilicate glass, each flask is hand-blown from tubing to achieve uniform wall thickness and enhanced mechanical strength.

Its flat base allows stable placement on benches or hot plates without additional supports, while the standard outer ground joint enables direct connection to condensers, adapters, and other laboratory glassware.

Available with multiple joint sizes to suit different setups.
