A microwave distillation apparatus is provided. The apparatus includes a microwave heating chamber having a plurality of walls. A vessel is located within the chamber for containing a liquid to be distilled. The vessel has a mouth for receiving the liquid. A connecting tube extends though an opening formed in one of the plurality of chamber walls. The connecting tube has a first end thereof for sealably engaging the mouth of the vessel, and a second end thereof extending outwardly from the chamber. A biasing assembly is located outside of the chamber, and engages the connecting tube with a biasing force to maintain the seal between the connecting tube and the mouth of the vessel. A distillate capture assembly is connected to the connecting tube for receiving vapors emitted from the liquid when heated, and for condensing the vapors into a liquid distillate for capture and storage.

[ I claim:] [1.] A microwave distillation apparatus, comprising:(a) a microwave heating chamber comprising a plurality of chamber walls;(b) microwave generating means for introducing microwave energy into said heating chamber;(c) a vessel located within said chamber for containing a liquid to be distilled, and having a mouth for receiving the liquid;(d) a connecting tube extending through an opening formed in one of said plurality of chamber walls, and having a bottom end thereof for sealably engaging the mouth of said vessel, and a top end thereof extending outwardly from said chamber;(e) a biasing assembly located outside of said chamber and engaging said connecting tube with a biasing force sufficient to maintain the seal between said connecting tube and the mouth of said vessel, said biasing assembly comprising:i. a housing surrounding the top end of said connecting tube, and mounted outside of said chamber adjacent to the opening formed in the chamber wall, said housing including an inwardly-extending top flange and an inside shoulder spaced apart from the top flange;ii. a vertically movable cylinder assembly located within said housing and surrounding the top end of the connecting tube, said cylinder assembly including a top ring engaging the connecting tube and an outwardly-extending bottom flange, the bottom flange of the cylinder assembly for contacting the inside shoulder of the housing to restrict movement of the cylinder assembly within said housing in a direction towards said vessel;iii. a coil spring surrounding the top end of the connecting tube, and located between and engaging the inwardly-extending top flange of the housing and the outwardly-extending bottom flange of the cylinder assembly, said spring normally urging the bottom flange of the cylinder assembly against the inside shoulder of the housing to thereby maintain the seal between the connecting tube and the mouth of the vessel; and(f) distillate capture means connected to said connecting tube for receiving vapors emitted from the liquid when heated, and condensing the vapors into a liquid distillate for capture and storage, said distillate capture means comprising vapor transfer means connected to the top end of said connecting tube for receiving vapors emitted from the liquid contained in said vessel when heated in said chamber, said vapor transfer means comprising:i. a surge bulb mounted in linear registration with said connecting tube, and having an opening therein sealably connected to the top end of said connecting tube;ii. an integrally formed neck of reduced diameter provided opposite the opening of the surge bulb for limiting the passage of heated liquid outwardly from the surge bulb: andiii. a deflector cylinder integrally formed with the neck, and in linear registration with the surge bulb and connecting tube, said deflector cylinder including a deflector plate for blocking the passage of heated liquid outwardly from the deflector cylinder while permitting free passage of vapors therethrough.
