Abstract: Filter caps 200, 400, 500, 600, 700 are provided that include internal geometry that modulate flow characteristics above the surface of a membrane filter held within the filter cap 200, 400, 500, 600, 700. The internal geometry in some cases provide for recirculation within the filter cap 200, 400, 500, 600, 700 that provides a cross flow element across the filter membrane that reduces clogging of the filter.
