Erlenmeyer flask
Conical chemistry vessel
An Erlenmeyer flask is a conical laboratory container with a flat bottom, wide base, and narrow neck.
The shape prevents spills during swirling and reduces evaporation.
It's standard equipment in chemistry labs for mixing, heating, and storing liquids: She swirled the solution in an Erlenmeyer flask.
Named for German chemist Emil Erlenmeyer.
