Erlenmeyer flask - Definition and Overview

Erlenmeyer flask

An apparatus feeding into an Erlenmeyer flask

An Erlenmeyer flask (also called conical flask) is a type of laboratory glassware which consists of an inverted conical base with a cylindrical neck. The main advantages in an Erlenmeyer flask are that it is less likely to tip over than a beaker and the smaller neck which slows evaporative loss. It can also be swirled without fear of the contents spilling. It is named after the German chemist Richard Erlenmeyer.

Sometimes to anchor an Erlenmeyer flask, a 'C' shaped lead or iron weight will be placed over the outside, to keep the flask firmly planted.
