What is the main use of a Bunsen burner in a laboratory?

The primary function of a Bunsen burner in a laboratory setting is to heat substances. Bunsen burners produce a flame by burning gas, typically natural gas or propane, allowing researchers to apply a controlled heat source directly to materials. This is essential for various experiments, such as sterilization, chemical reactions, and the evaporation of solvents. The flame can be adjusted to create different temperatures, offering versatility for specific heating needs in scientific work. The ability to precisely control the heat makes the Bunsen burner a fundamental tool in biological and chemical laboratories.
