a piece of equipment used in a laboratory that can burn gas and create flames
A Bunsen burner is a small, adjustable laboratory device used to produce a flame for heating or sterilizing substances. It is powered by gas and has a nozzle that controls the size and intensity of the flame. The burner consists of a metal tube, with an air supply regulator at the bottom to adjust the amount of oxygen, which affects the flame's temperature. Bunsen burners are commonly used in scientific experiments where precise heat is needed for tasks like boiling liquids, heating substances, or conducting chemical reactions.
