Introduction to the Bunsen Burner

JoVE 5035

The Bunsen burner, named after and co-designed by Robert Bunsen in 1854, is a common laboratory instrument that produces a hot, sootless, non-luminous flame. The Bunsen Burner allows for precise regulation of the mixing of gas and oxygen in its central barrel before combustion, which ignites the flame. By manipulating the Bunsen burner, both the size and temperature of the flame can be controlled. Among other uses, the heat of a Bunsen burner flame can be used to create a convection current, which heats the space above the flame and lifts any particulates in the air up and away from the cooler air underneath it, keeping this work area sterile. Working with an open flame requires extra caution. Always remember to secure any loose hair, clothing, or accessories before lighting a Bunsen burner and to always have the proper safety equipment, like a fire extinguisher and/or a fire blanket, on hand. Taking the time to understand how to use a Bunsen burner and what safety equipment to have on hand will allow you to operate this useful laboratory tool with safety and confidence.
