This high-quality stainless steel & ceramic butane burner replaces alcohol lamps in siphon coffee maker setups. Mini-tank hold 40ml (somewhat more than 1 liquid ounce) of butane, which provides up to 75 minutes of heat. The unit includes a built-in electronic igniter, a snuffer and the appropriately sized nozzle adapter to lighter butane cans. Please, note that this unit can be used with a balancing siphon coffee maker, but it will not be extinguished when the pot rises, before kick-down. (Simply remove the burner and extinguish it manually.)
