The Erlenmeyer flask cannot be heated directly. The Erlenmeyer flask is a common glass instrument used in chemical experiments. Because its bottom is flat, if it is heated directly, the bottom will be heated unevenly and explode. When heating the Erlenmeyer flask, a pad should be placed underneath it. A layer of asbestos mesh.

Erlenmeyer flasks are more common in chemical laboratories and are generally used in titration experiments to prevent the titrant from splashing out when it is dropped and causing experimental errors.

Erlenmeyer flasks can also be used to prepare gases, contain reactants, quantitative analysis, reflux heating, etc. because their structures are relatively stable and not easy to tilt.

The Erlenmeyer flask, also known as Erlenmeyer flask, Erlenmeyer flask, Erlenmeyer flask, Olenmaier bottle, etc., was invented by the German chemist Richard Olenmaier in 1861.
