Bunsen Burner is a kind of gas burner that creates a safe, smokeless, hot, and non-luminous flame which can be used for various scientific experiments and research.
In 1857, German scientist Robert Bunsen and his lab assistant Peter Desaga invented the Bunsen burner and named it after his surname. It generates a single open gas flame that functions in combustion, sterilization, or heating.
Luminous and non-luminous flame are the two types of flame. When the air-hole is opened, the bright flame will change into a non-luminous flame which can be seen with an orange brilliant flame.
