Abstract

Vaporization devices and methods of operating them are described. In particular, cartridges are described for use with a vaporizer device body in which a cartridge is received in a receptacle of the vaporizer device body in one of two orientations. A heater chamber in the cartridge may be proximate to a bottom end of the cartridge and/or disposed between a storage compartment configured to hold a vaporizable material and the bottom end of the cartridge.
