For a mobile flame that is safe to the extreme, Scientific Laboratory Supplies recommends the Integra FireBoy.
Based on sensor technology, the Integra FireBoy flame ignites in a non-touch mode, with unintentional ignitions eliminated by a clearly defined sensor range.
It can be used with a permanent power and gas supply, but by simply adding a gas cartridge adapter, it can be turned into a versatile and mobile stand alone unit.
It is described as a must have item for all cabinet users, field work, or those who do not have, or prefer not to use, a gas supply.
