Abstract: The present invention is a vaporizer apparatus (1) and method for uniformly extracting active ingredients of specimen of crude natural product, or inert particulate matrix impregnated with volatile substances without pyrolysis which uses hot air (2), or a heated inert gas stream to volatilize the specimen. The heated air or gas in introduced from below (from either a hot air gun or a high-pressure tank connected to a heat exchanger), and ascends through in most embodiments through a permeable support structure (4) (e.g., fritted glass disk, etc.) subsequently causing specimen particules disposed on the permeable support structure to be suspended within the confines of an isolation chamber (5).
