Bunsen Burner (Pack of 2)





  • Bunsen Burner  in use today safely burns a continuous stream of flammable gas such as natural gas or  liquefied petroleum gas.
  • The hose barb is connected to a gas nozzle on the laboratory bench with rubber tubing.
  • Most laboratory benches are equipped with multiple gas nozzles connected to a central gas source, as well as vacuum, nitrogen.
  • The gas then flows up through the base through a small hole at the bottom of the barrel and is directed upward.
  • There are open slots in the side of the tube bottom to admit air into the stream using the Venturi effect.
  • The gas burns at the top of the tube once ignited by a flame or spark.
  • The most common methods of lighting the burner are using a match or a spark lighter.
  • The amount of air mixed with the gas stream affects the completeness of the combustion reaction.
  • The air flow can be controlled by opening or closing the slot openings at the base of the barrel, similar in function to the choke in a carburettor.
  • Brass Bunsen Burner is used in laboratories for educational research and in the pathological lab.
  • It produces a single open gas flame, which is used for heating, sterilization, and combustion.
