Abstract: A crossflow filter includes a rigid cylindrical inner wall and a rigid cylindrical outer wall inner with an inelastic filter membrane positioned therebetween defining a retentate channel inside the filter membrane and a permeate channel outside the filter membrane. Further, the filter includes transition channels shaped and connected to the inner and outer walls to deliver a flow of fluid from an inlet port to the retentate channel and to capture flow flowing longitudinally along the cylindrical inner and outer walls from both the retentate and permeate channels to respective outlet ports.
