- Flat-bottomed flasks are widely used in organic synthesis and inorganic preparation experiments, and are mostly used in organic experiments that require long-term reactions.
- Flat-bottomed flasks are generally not used as heated reactors due to their flat bottoms and uneven heating when heated. When heating, the flat-bottomed flask should be covered with asbestos mesh, which should not exceed 1/2 of the volume of the flask, to prevent too much water from being easily splashed during boiling or the pressure in the bottle is too high and it may explode
