摘要： An improved automatic filtration and extraction device is disclosed which comprises a base 17 defining at a top end a broadened cavity area which tapers downwardly and inwardly from the top end to define a chamber for a portion and then defines a plurality of effluent outlets at the bottom end each extending from the chamber to an outer surface of the body. Sealers 42 are adapted to each of the effluent outlets and are moveable between a first closed position sealing the effluent outlet and a second open position to allow the passage of effluent through the effluent outlet. A filter 110 is detachably and removeably adapted over the broadened cavity area. A solvent provider 90 is adapted to the base whereby various solvents are provided to the broadened cavity area. A circuit 200 is connected at one end to a power source, and the programmable memory to access and direct the sequence of events after an initial event. A programmable memory is provided for a sequence of events and is connected to the base. A vacuum is adapted to each of the effluent outlets each having an "ON" position whereby a vacuum is provided to induce effluent flow through the effluent outlet and to seal all other outlets, and an "OFF" position eliminating vacuum to that effluent outlet.

Seals are adapted to each of the effluent outlets and are moveable between a first closed position sealing the effluent outlet and a second open position to allow the passage of effluent through the effluent outlet. A filter is detachably and removably adapted over the cavity area. Various solvents are provided to the cavity area through a solvent provider. A circuit with programmable memory accesses and directs a sequence of events after an initial event. A vacuum connected to each of the effluent outlets each induces effluent flow through an effluent outlet while sealing all other outlets. A removable valve assembly attaches to the sample bottle such that the bottle and valve assembly may be removed as a single unit from the base. An extraction sequence may be manually interrupted for removal of the sample bottle to another station.
