Boiling Flasks

Boiling flasks are used for heating and boiling of liquids. The flasks are designed to have round bodies with long, thin necks to facilitate uniform heat distribution and minimize evaporation. Boiling flasks are typically made of borosilicate glass, which is resistant to thermal shock and chemicals. Some boiling flasks have rounded or conical bottoms and need support to stand upright, while others have flat bottoms and can stand alone.
