Abstract:
1. An apparatus for separating at least two discrete volumes of a composite liquid into at least a first component and a second component, the apparatus comprising: a centrifuge rotor adapted to rotate about a rotation axis, a plurality of separation cells, each of the plurality of separation cells adapted to receive a separation bag of a set of fluidly interconnected bags, the set comprising at least the separation bag containing a volume of composite liquid, and at least one component bag; a plurality of cavities, each of the plurality of cavities adapted to receive at least one component bag; a plurality of valves, each of the plurality of valves being adapted to control fluid flow between parts of the set of interconnected bags, each of the plurality of valves comprising a jaw mounted on a shaft, the jaw being adapted to apply radio frequency energy to an adjacent tube to seal the tube, wherein each of the plurality of valves further comprises a cam mounted on the shaft, the cam guiding the jaw in a translating and rotating motion from a load position to an open position and in a translating motion from the load position to a closed position; a plurality of springs, wherein each of the plurality of springs is coupled to a shaft of one of the plurality of valves and being adapted to maintain a jaw of the plurality of valves in contact with a tube as the tube is sealed; and a controller electrically connected to the plurality of valves, the controller controlling a status of the plurality of valves.
