Claim:
1. A device for washing a suspension of cells comprising: a bowl-shaped basin having an inner surface, an outer surface, an open top end, a bottom end, and a central axis extending from the top end to the bottom end; an inlet port formed into the basin for continuously delivering a wash solution into the basin to fill the basin such that the wash solution overflows from the open top end, the inlet port being angled such that the wash solution circulates around the basin about the central axis, wherein the bowl-shaped basin maintains circular flow of the wash solution about the central axis, wherein a suspension of cells can be delivered into the circulating wash solution, and wherein the circulating wash solution forces the cells to settle at the bottom of the basin where the cells can be extracted; a filter at the top end permitting passage through the open top end of overflowing wash solution and retaining cells within the basin; and a lid assembly comprising an annular lower unit and an annular upper unit, wherein the filter is positioned between the lower unit and the upper unit.
