Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing having a storage chamber and a dispensing chamber, and a vaporization chamber in communication with the dispensing chamber. The storage chamber is configured to hold a first fraction of a vaporizable material and the dispensing chamber is configured to hold a second fraction of the vaporizable material. The dispensing chamber is further configured to selectively dispense at least a first portion of the second fraction of the vaporizable material through at least one dispense opening in response to generation of one or more pressure pulses created within the dispensing chamber. The vaporizable chamber is configured to receive the dispensed vaporizable material from the dispensing chamber for vaporization by a first heating element to form a vaporized material. Vaporizer devices are also provided.
