What is the use of a Bunsen burner?

In short please. Thank you

A Bunsen burner, if hooked to a gas supply, is a device for heating materials.

A small laboratory burner consisting of a vertical metal tube connected to a gas source and producing a very hot flame from a mixture of gas and air let in through adjustable holes at the base. It is mainly used to heat chemicals.

A Bunsen burner is a commonly used laboratory tool that produces a controlled flame. It is primarily used for heating purposes in scientific experiments and processes, such as sterilization, heating substances in test tubes or beakers, and performing various chemical reactions. The flame can be easily adjusted by altering the amount of air and gas flowing into the burner, making it a versatile tool for different applications in the laboratory.
