A Bunsen burner is primarily used in laboratories for heating, sterilization, and combustion. It produces a hot, non-luminous, smokeless flame by mixing gas with oxygen before burning, which allows for controlled and efficient heating. Common uses of a Bunsen burner include:

  • Heating substances in beakers, test tubes, and other containers during experiments.
  • Sterilizing laboratory tools such as loops and needles, especially in microbiology.
  • Performing flame tests to identify certain elements based on the color of the flame.
  • Glass blowing to soften and shape glass.
  • Drying samples by evaporating moisture.
  • Conducting chemical reactions that require controlled heat.
  • Determining melting and boiling points of substances.
  • Dehydration of complexes, drying salts, and moisture analysis.

The adjustable air inlet of the burner allows the flame temperature and characteristics to be controlled, making it a versatile tool in scientific research and education.
