A Bunsen burner is an apparatus used in Laboratoire to heat, to sterilize, and various other uses.

One wrongly allots his invention to Robert Wilhelm Bunsen. The Bunsen burner does not owe him its name, only because its assistant of laboratory, Peter Desdega, had improved in 1855 a model created by Michael Faraday.

This nozzle burns, in full safety, a continuous gas flow without extension risk of the flame by the tube towards the gas tank.
