Patent ID: 8512566

Claim:
A gravity assisted disposable apparatus for separating a biological sample into two or more distinct submaterials through sedimentation comprising: a sample delivery conduit; and a bag-set in fluid communication with the sample delivery conduit and wherein said bag-set is a functionally-closed fluid path comprising; a tubing assembly for transferring the biological material through the bag-set; a separation assembly in fluid communication with the tubing assembly configured to receive the biological sample from the sample delivery conduit and to allow for sedimentation of a submaterial from the biological material; and a filter assembly in fluid communication with the tubing assembly and the separation assembly, wherein said filter assembly is configured; to receive the biological sample and at least one submaterial from the separation assembly through the tubing assembly for filtering; to return retentate material to the separation assembly through a retentate conduit; to deliver permeate material to the separation assembly through a permeate conduit; and to return permeate material from the separation assembly to said filter assembly through the tubing assembly.
