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.
Claims21
A filter cap for bioprocessing comprising:
- a conical shaped portion, where the conical shape is configured to distribute fluid over a surface of a filter membrane;
- and
- at least one flow conduit within the conical shape portion, wherein the flow conduit is capable of providing at least one of recirculating flow, vortex flow, spiral flow, and/or cross-flow across the membrane.
