Boiling Flasks

Boiling flasks are round-bottomed laboratory glassware designed for uniform heating of liquids during boiling and distillation processes. Made from heat-resistant borosilicate glass, they evenly distribute heat, reducing the risk of thermal stress. These flasks are commonly used in chemistry labs for reactions and separations that require consistent heating.

Specifications
