An Erlenmeyer flask, also known as a conical flask (British English) [1] or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860.
A flat bottomed flask is used in a chemistry laboratory for experiments involving the collection and measurement of liquids, mixing solutions and culture media. The design and construction of the flat bottomed flask allows it to stand alone on the laboratory bench.

The flasks are often long necked; sometimes they have the incision on the neck, which precisely defines the volume of flask. They can be used in distillations, or in the heating a product. These types of flask are alternatively called Florence flasks. Flasks with flat bottom.
Flat-bottom flasks are round flasks, usually composed of a single neck, which are used to heat compounds in distillation or other reactive reactions. They are usually used to contain liquids and to heat them.
Round-bottom flasks (also called round-bottomed flasks or RB flasks) are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work. [1] They are typically made of glass for chemical inertness; and in modern days, they are usually made of heat-resistant borosilicate glass.
