Abstract: A concentrate adaptor for a vaporizer device includes a reservoir and a base. The reservoir holds a concentrate. The reservoir is positioned within a vessel of the vaporizer device and is heated by a heating element of the vaporizer device to transfer heat to the concentrate, thereby generating an aerosol for inhalation by a user. The reservoir includes a sidewall surrounding an interior volume of the reservoir. The reservoir also includes a capillary structure positioned along the sidewall configured to direct the concentrate to the sidewall to be heated by the heating element.
