2. 4. A Bunsen burner, named after Robert Bunsen, is a kind of gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.[1][2][3][4][5]. It has an air hole to allow entry of air into the barrel. A Bunsen burner is made up of the base, a barrel with air holes, a collar, a needle valve and a gas hose. The Bunsen burner has a variety of uses in different fields. An efficient Bunsen burner is purely metallic (except the gas tubing) and has five main parts: 1. The following features make them safe burners: Flame monitoring: To prevent dangerous gas leakage, safety Bunsen burners automatically try to reignite the flame if it accidentally extinguishes.Should it for any reason fail to do so, safety burners â¦ This reduced mixing produces an incomplete reaction, producing a cooler but brighter yellow, which is often called the "safety flame" or "luminous flame". For the safety and â¦ Desaga created adjustable slits for air at the bottom of the cylindrical burner, with the flame igniting at the top. A Bunsen burner is used in a laboratory to heat substances during an experiment. Michael Faraday then improved the design of the burner. Biologists use the burner flame to sterilize tools used to handle bacteria and other sensitive microorganisms. A Bunsen burner is a laboratory device used to heat substances for various experiments. Two years later Bunsen published a description, and many of his colleagues soon adopted the design. A Bunsen burner is a portable gas burner used for heating, burning and sterilising materials in a laboratory. This flame is hotter and preferred for heating in the laboratory because it is easier to control than a wavy, luminous flame. A Bunsen burner is also used in microbiology laboratories to sterilise pieces of equipment[7] and to produce an updraft that forces airborne contaminants away from the working area.[8]. PLAY.
