A beaker is a simple container for liquids, very commonly used in laboratories. Beakers are generally cylindrical in shape, with a flat bottom. Beakers are available in a wide range of sizes, from 1mL up to several litres. A right circular cylinder An elliptic cylinder In mathematics, a cylinder is a quadric surface, with the following equation in Cartesian coordinates: This equation is for an elliptic cylinder, a generalization of the ordinary, circular cylinder (a = b). ...

They may be made of glass (very often Pyrex) or of plastic. Beakers used for holding solutions of corrosive chemicals, such as acids, should be made of Teflon or other materials resistant to corrosion, eg borosilicate glass.

Beakers may be covered, perhaps by a watch glass, to prevent contamination or loss of the contents. Beakers are often graduated, marked on the side with lines indicating the volume contained. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. The accuracy of these marks can vary from one beaker to another.
