Erlenmeyer Conical Flask, Borosilicate 3.3 with Narrow Neck

This Erlenmeyer conical flask is made from borosilicate 3.3 glass and has a narrow, rimmed neck. An Erlenmeyer flask, also called a conical or titration flask, has a flat bottom, a conical body and a cylindrical neck.

The wide base tapers up to a short vertical neck. These flasks are often graduated and have a ground glass or enamel spot you can write on in pencil.

The mouth usually has a beaded lip that can be stoppered or covered. Some flasks have a ground glass neck instead, for special stoppers or for connecting to other apparatus.
