Patent ID: 7832566

Claim:
A separation system for use in a centrifuge device, comprising: a container having a side wall sealed to and extending from a first end wall to a second end of the container, wherein the container is operable to contain a multi-component sample; a separation system disposed in said container in a separation region of said container and near said first end wall and operable to contact said first end wall, said separation system including at least a first separation member operable to move in said separation region based at least in part on a density of said multi-component sample positionable in said separation region, said separation system further including a second separation member and a third separation member operably interconnecting said first separation member and said second separation member; and a filtration member disposed in a filtration region of said container between said separation system and said second end of said container; wherein said multi-component sample is operable to be positioned in said filtration region of said container from an exterior of said container and a portion of said multi-component sample is operable to be filtered by passing through said filtration member in said filtration region to said separation region of said container; wherein said first separation member and said second separation member are connected to one another during separation of said multi-component sample; wherein said third separation member has an internal passage that allows access to a volume between said first separation member and said second separation member; wherein said first separation member is movable relative to said second separation member along at least a portion of a length of said third separation member.
