A bubbler () for delivering liquid or solid metalorganic compounds to a reactor site. The bubbler has an inner and outer chamber and has a member () positioned between its inlet () and outlet () that is provided with a plurality of apertures therein. The member () is preferably in the form of a perforated disc having a predefined density of apertures therein to provide optimum pick up and flow of carrier gas through the bubbler.
