iolite hand held vaporizer offers vaporizing with total convenience, hands-down simplicity, pocket-size portability, and durability. iolite vaporizer is butane operated and requires nothing but butane! Pull the heater cover off to reveal the aluminum heat-pin 500 mg/0.01 oz. tobacco chamber. Fill iolite with butane, and once filled up, switch the button to the “on” position in order to open the main valve which will allow the butane to flow through from its massive 0.122 oz. tank creating a “hissing” sound. Now push the ignitor to active heats up-to 374°F/190°C. Vaporize anywhere and anytime in just 45-seconds with iolite vaporizer. The iolite operates up to 120 minutes.
