Round Bottom Flask – Narrow Neck (Borosilicate Glass)

Our Round Bottom Narrow-Neck Flasks are essential for heating, boiling, distillation, and chemical synthesis in research, industrial, and educational laboratories. The classic spherical shape ensures even heat distribution, reducing hot spots and improving reaction efficiency. The narrow neck supports controlled pouring, reduced evaporation, and compatibility with standard stoppers, making these flasks ideal for both open and closed-system experiments. Crafted from premium borosilicate glass, they deliver exceptional durability and chemical resistance in demanding laboratory environments.

Key Features

Even Heat Distribution
