The purpose of a beaker is to hold various types of liquids. A beaker often has a wide bottom and a narrow top. Beakers are typically used in laboratories and schools so that scientists and students are able to work with chemicals safely and easily.
The types of beakers that scientists and students use are made from a special type of glass. The special glass ensures that the beaker is not damaged by any of the chemicals that are placed into the vessel. A beaker usually has markings on the outside to help the user gauge the amount of liquid the container holds.
