A self-contained laboratory burner. Ideal as a safer alternative to alcohol burners. Burner assembly mounts on a butane canister. With the gas control valve wide open the “burn time” for a fresh canister should be approximately three hours. Fully adjustable gas control valve. Air supply is fully adjustable using knurled screw knob. A 3" diameter drip catcher is permanently mounted in the burner assembly. The drip catcher also acts as a heat dissipator to prevent burner heat from being transferred to the area of the burner assembly where the gas control is adjusted.
