ABSTRACT:
A sealing member for a multi-well microfiltration plate comprises a flexible sealing material which, in response to the application of differential pressure, will flex or collapse in the direction of the filtration along the contour of each individual well. A process maintains a differential pressure substantially constant over a multi-well microfiltration plate comprising placing said flexible sealing member over that surface of the plate having well openings, stretching the flexible sealing member so as to seal the perimeter of each individual well, creating a differential pressure around said plate covered with said seal and filtering a media from each occupied well at a rate independent of the filtration rate of any other well while maintaining a substantially constant differential pressure around the plate until filtration in the last well containing media is complete.
