ABSTRACT:
Methods of separating selected blood components separate blood by centrifugation in a rotating chamber into a first separated blood component, a residual blood fluid, and an interface between the first separated blood component and the residual blood fluid. The methods withdraw the first separated blood component out of the rotating chamber through a first outlet port, and withdraw the residual blood fluid out of the rotating chamber through a second outlet port. During the separation step, the methods accumulate a second separated blood component in the interface without withdrawal from the rotating chamber by controlling the position of the interface within the rotating chamber at a location spaced away from flow communication with both the first and second outlet ports. The methods terminate the withdrawing steps either when a desired volume of the second separated blood component has accumulated in the location or after a selected time period, and shift the location of the interface within the rotating chamber into flow communication with one of the first and second outlet ports. The methods withdraw the second separated blood component from the rotating chamber through the one outlet port.
