Clearomisers or tanks have become the most used type of electronic cigarette cartridge. Ever improving technology and innovation have helped them to overtake the humble (and still very effective) cartomiser.
A clearomiser has a tank, made from either polycarbonate or pyrex which is used to contain the e-liquid. The e-liquid is then vaporised by the atomiser which is then sucked through the chimney to the drip tip and into your mouth when you inhale.
