Each plate includes a plurality of wells, which, when the filter plate is placed in nesting relationship with the receiver plate, each filter plate well has a corresponding receiver plate well into which it extends. The receiver plate wells are of a non-uniform cross-section in order to increase the gap between the outer walls of the filter plate wells and the inner walls of a corresponding receiver plate well when the receiver plate and filter plate are in nesting relationship. The increased gap size reduces wicking and cross-contamination. A multi-section well of maximum cross-section in an upper region and a minimized cross-section in a lower region, with a gradual transition between the regions, is thus provided.
