Abstract:
1. A method of processing biological fluid comprising: a) providing a biological fluid filtration device having a first inlet, wherein the first inlet including an inlet end and an outlet end, and a first outlet and at least one first filter element interposed between the first inlet and the first outlet, and defining a first fluid flow path, that is completely independent of and isolated from a second fluid flow path, and that flows from the first inlet through the first filter element into the first outlet; said biological fluid filtration device further having a second inlet, wherein the second inlet includes an inlet end and an outlet end, wherein the outlet end of the second inlet is completely isolated from the outlet end of the first inlet within the device, and a second outlet and at least one second filter element interposed between the second inlet and the second outlet, and defining a second fluid flow path, that is completely independent of and isolated from the first fluid flow path, and that flows from the second inlet through the second filter element into the second outlet; said biological fluid filtration device further including a solid partition wall interposed between the first fluid flow path and the second fluid flow path, with said solid partition wall isolating the entire first fluid flow path, from the first inlet to the first outlet, from the entire second fluid flow path, from the second inlet to the second outlet; wherein, flow into said first outlet stops when flow into said first inlet stops, and wherein, flow into said second outlet stops when flow into said second inlet stops.
