Descripción

Conical flasks are typically used in titration experiments. In order to prevent the titration solution from splashing out of the bottle, causing experimental errors, the bottle is placed on a magnetic stirrer and stirred.
Cone bottles can also be used in ordinary experiments to make gas or as a reaction vessel. Its tapered structure is relatively stable and will not fall.
