Abstract

The invention discloses a distribution plate for supplying crossflow filtration cassettes, which comprises a surface, two opposite end walls, two opposite side walls, a feed channel in fluid communication with a feed inlet port and with a plurality of feed apertures; a retentate channel in fluid communication with a retentate outlet port, and with a plurality of retentate apertures; and a permeate channel in fluid communication with two permeate outlet ports and with a plurality of permeate apertures;wherein the feed channel, the retentate channel and the permeate channel extend in a direction essentially parallel with one or both side walls;wherein the feed apertures are grouped at a first area on the surface, the retentate apertures are grouped at a second area on the surface;wherein the permeate apertures are located at the first and/or the second area; andwherein a plurality of permeate connector channels extend inside the plate from at least one region of the permeate channel, adjacent the permeate outlet ports and the permeate connector channels provide fluidic communication between the permeate apertures and the permeate channel.
