Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.
Schlenk flask, which is a spherical flask with a ground glass opening and a hose outlet and a vacuum stopcock. The tap makes it easy to connect the flask to a vacuum-nitrogen line through the hose and to facilitate the carrying out of a reaction either in vacuum or in an atmosphere of nitrogen.
A chemistry test tube typically has a flat bottom, a round bottom, or a conical bottom. Some test tubes are made to accept a ground glass stopper or a screw cap . They are often provided with a small ground glass or white glaze area near the top for labelling with a pencil.
An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

Such a flask has a wide mouth and is known as a Kohlrausch volumetric flask. This kind of volumetric flask is commonly used in analysis of the sugar content in sugar beets . While conventional volumetric flasks have a single mark, industrial volumetric tests in analytical chemistry and food chemistry may employ specialized volumetric flasks ...
Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface. Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface. Florence flasks typically ...
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.
