Patent ID: 8337380

Claim:
An apparatus for separating at least two discrete volumes of a composite liquid into at least a first component and a second component comprising a centrifuge rotor adapted to rotate about a rotation axis, at least one separation cell, adapted to receive a separation bag of a set of fluidly interconnected bags, said set comprising at least said separation bag containing a volume of composite liquid, and at least one component bag, a cavity adapted to receive at least said component bag, a plurality of valves, the valves being adapted to control fluid flow between parts of the set of interconnected bags, at least one of said valves comprising a jaw mounted on a shaft, said jaw being adapted to move from a load position allowing at least one tube to be placed adjacent said valve to an open position over said tube and from said open position to a closed position constricting fluid flow through said tube, and a controller electrically connected to said valves, said controller controlling the status of said valves, wherein said valves further comprise a cam mounted on said shaft, said cam guiding said jaw in a translating and rotating motion from said load position to said open position and in a translating motion from said load position to said closed position.
