is supplied to the heating rod 48 the heating rod 48 generates heat which is transferred to the heating conduit 46 and ultimately to the herbal receptacle 36 preferably via conduction between the heating conduit 46 and the herbal receptacle 36 in other words the herbal receptacle 36 is preferably disposed in contact with the heating conduit 46 to facilitate heat transfer therebetween it is understood that the herbal products 14 vaporize at a vaporization temperature for instance with regard to marijuana approximately 20 of the htc is released at a vaporization temperature below 250 u00b0 f at temperatures between 250 u00b0 f 350 u00b0 f 25 40 of the htc is released along with a minor amount of carbon marijuana burns at approximately 380 u00b0 f to release approximately 60 htc certain aspects of the vaporizer device 10 are directed toward maintaining the temperature of the herbal receptacle 36 within a certain vaporization temperature range for instance the vaporization range for marijuana may be from 210 u00b0 f to 220 u00b0 f the vaporization range may be pre programmed into the device 10 for various herbal products 14 or alternatively the device 10 may include a user interface such as a touch screen dial or the like to allow a user to set the vaporization range those skilled in the art will appreciate that a few drops of water alcohol or glycol improves the vaporization efficiency at lower temperatures along these lines the vaporizer device 10 may include a temperature control unit 64 in electrical.
