Claim 9:
10. A method of manufacturing a sample plate for automated exchange of buffer solutions comprising:
loading a filter having a peripheral edge into a plurality of reservoirs, wherein each reservoir of the plurality of reservoirs comprises a side wall, a ring shaped inner ridge, and a filter attachment region comprising a ring shaped channel defined by the side wall and the ring shaped inner ridge, wherein the filter has a diameter configured to accommodate a height of the ring shaped inner ridge so that the peripheral edge of the filter may be secured to each reservoir at the filter attachment region;
thermally sealing the filter peripheral edge to the filter attachment region;
filling the ring shaped channel with an adhesive; and
curing the adhesive to adhesively seal the filter peripheral edge to the filter attachment region;
wherein the filter attachment region maintains fixation of the filter peripheral edge to each reservoir at a pressure differential across the filter of at least about 30 psig.
