This unique lab burner will produce temperatures well over 1350 ºC. Can be used as both a Bunsen burner (on its side) or as a torch (upright). The burner has a fuel capacity of over one hour and can be easily refilled with standard butane canister fuel. An ON/OFF safety switch allows the flame to be controlled for on and off use or can be set for a continuous flame. Note: Burner is sold empty. The butane fuel is sold separately.
