Spirit lamp

An alcohol burner or spirit lamp is a piece of laboratory equipment used to produce an open flame. It can be made from brass, glass, stainless steel or aluminium.

Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, as their flame is limited to approximately two inches (5 centimeters) in height, with a comparatively lower temperature.

While they do not produce flames as hot as other types of burners, they are sufficient for performing standard microbiology laboratory procedures and can be used for flame sterilization of other laboratory equipment.

Typical fuel is denatured alcohol, methanol, or isopropanol. A cap is used as a snuffer for extinguishing the flame.
