Bunsen Burner

Bunsen Burner, a gas burner used widely in scientific laboratories. One of the scientist's basic tools, it is used for heating chemicals, boiling water, sterilizing small objects, preparing microscopic slides, bending glass tubing, and for many other purposes. The burner is named for Robert Wilhelm Bunsen, a German chemist who is credited with its invention.

The Bunsen burner consists of a straight metal tube, about five inches (13 cm) long, fastened to a stand. The bottom is connected by rubber tubing to a source of illuminating gas. Adjustable openings at the base of the burner admit air. The mixture of gas and air produces a very hot flame. Nozzles of various types can be fitted to the top of the burner to control the flame's shape.
