Bunsen Burner, heating device widely used in laboratories because it provides a hot, steady, smokeless flame. It is named for the German chemist Robert Wilhelm Bunsen, who adapted the concept of a gas-air burner in 1855 and popularized its use. The burner is a short, vertical tube of metal connected to a gas source and perforated at the bottom to admit air. The flow of air is controlled by an adjustable collar on the tube.
