1. A method of producing a multiple well filter plate comprising:selecting a preformed plate with top and bottom surfaces, said bottom surface being suitable for affixing a filter thereto, said plate having a plurality of holes passing through said plate from said top surface to said bottom surface,

1. A method of producing a multiple well filter plate comprising:selecting a preformed plate with top and bottom surfaces, said bottom surface being suitable for affixing a filter thereto, said plate having a plurality of holes passing through said plate from said top surface to said bottom surface, selecting a filter suitable for filtering solutions, forming wells by adhering a top surface of the filter to the bottom surface of the plate, and making a series of cuts into the top surface of the filter before adhering the filter to the bottom surface of the plate so as to allow for adhesion to occur. 2. A method of producing a multiple well filter plate comprising:selecting a preformed plate with top and bottom surfaces, said bottom surface being suitable for affixing a filter thereto, said plate having a plurality of holes passing through said plate from said top surface to said bottom surface, selecting a filter suitable for filtering solutions, and forming wells by adhering a top surface of the filter to the bottom surface of the plate wherein the bottom surface of the plate to which the filter is bonded has a series of troughs formed around the holes into which the adhesive is placed. 3. A method of producing a multiple well filter plate comprising:selecting a preformed plate with top and bottom surfaces, said bottom surface being suitable for affixing a filter thereto, said plate having a plurality of holes passing through said plate from said top surface to said bottom surface, selecting a filter suitable for filtering solutions, forming wells by adhering a top surface of the filter to the bottom surface of the plate wherein the first surface of the filter having cuts through at least a portion of the depth of the first surface, the filter being attached by its first surface to the bottom surface of the plate so as to form a seal between the plate bottom and the seal being an adhesive bonded to the cuts in the first surface of the filter. 4. A method of producing a multiple well filter plate comprising:selecting a preformed plate with top and bottom surfaces, said bottom surface being suitable for affixing a filter thereto, said plate having a plurality of holes passing through said plate from said top surface to said bottom surface, selecting a filter suitable for filtering solutions, and forming wells by adhering a top surface of the filter to the bottom surface of the plate wherein the filter is an ultrafiltration filter, the first surface of the filter having a smaller pore size than the second surface, the first surface of the ultrafiltration filter having cuts through at least a portion of the depth of the first surface, the ultrafiltration filter being attached by its first surface to the bottom surface of the plate so as to form a seal between the plate bottom and the ultrafiltration filter and the seal being an adhesive bonded to the cuts in the first surface of the filter. 5. The method of claim 1 wherein the filter is selected from the group consisting of microporous and ultrafiltration filters.6. The method of claim 2 wherein the filter is selected from the group consisting of microporous and ultrafiltration filters.7. The method of claim 1 wherein the filter is a microporous filter.8. The method of claim 1 wherein the filter is a ultrafiltration filter.9. The method of claim 2 wherein the filter is a microporous filter.10. The method of claim 2 wherein the filter is an ultrafiltration filter.
