Meiwlaby 200ml Borosilicate Glass Flat-Bottom Boiling Flask Single Neck with Standard Ground Joint 24/29

The MEIWLABY S264200 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, this flask features a standard 24/29 outer joint for seamless integration with condensers, adapters, and other ground-glass components.

Its flat base allows stable placement on hot plates or benches without additional supports, while the heavy-wall construction provides enhanced durability and resistance to thermal shock.

Each flask is hand-blown from tubing, ensuring uniform wall thickness and consistent performance in demanding laboratory environments.
