Abstract:
A device for vaporization and delivery of a volatile source material without combustion or significant denaturation of the source material comprising, in combination, (i) a heating system including a means for heating and a heating chamber, (ii) a source material holder which is insertable in and removable from the heating chamber, and (iii) a temperature control means which maintains the temperature of operation of the heating system substantially constant within a range of about .+-.10.degree. C. both when the material holder is in the heating chamber and when it is removed from the heating chamber during use,wherein the heating system comprises an electrical resistance heater in a metal body which is of sufficient mass to maintain the + or -10.degree. C. temperature range and which has at least one air flow hole and is connected to a pump means which forces air through the air flow hole at an air flow rate of between about 0.5 and 5 liter per min.
