Bunsen burner

A Bunsen burner is a common laboratory instrument used to produce a controlled flame for heating substances. It works by mixing natural gas or another fuel with air to generate a hot, adjustable flame. The heat generated is useful for experiments that require precise heating, sterilization, or flame analysis. The device has an adjustable air supply to change the flame’s temperature and style—either a luminous, cooler flame or a hot, non-luminous flame. Its design allows for safe, consistent heat application in scientific and educational settings.
