conical flask
Tapered glass container
A conical flask is a laboratory glass container with a flat bottom, wide base, and sides that taper to a narrow cylindrical neck.
The shape allows swirling without spillage and reduces evaporation.
Also called an Erlenmeyer flask after its inventor.
She heated the solution in a conical flask over a Bunsen burner.
