Abstract: Single-use integral chromatography unit having an inlet and an outlet, and comprising one or more plates or pairs of filter plates interposable between a pair of end plates. In certain embodiments, each of the filter plates comprises a polymeric framework with one or more membranes supported therein. The filter plates and end plates may be assembled to form a substantially fixed, substantially water-tight, integral stack. Fluid entering the unit through a common inlet passes the membrane or membranes of each filter plate substantially contemporaneously prior to exiting the unit through a common outlet (cf, “parallel” flow). The assembly is a modular design, as multiple pairs of plates can be stacked in a suitable holder to form a single chromatography unit.
