The invention is directed to a centrifugation bowl with a rotating core. The centrifugation bowl includes a rotating bowl body which defines a primary separation chamber. The core, which is generally cylindrically shaped and is disposed within the bowl body, defines a secondary separation chamber. A stationary header assembly may be mounted on top of the bowl body through a rotating seal. The stationary header assembly includes an inlet port for receiving whole blood and an outlet port from which one or more blood components are withdrawn. The inlet port is in fluid communication with a feed tube that extends into the primary separation chamber. The outlet port is in fluid communication with an effluent tube that extends into the bowl body. The effluent tube includes an entryway at a first radial position relative to a central, rotating axis of the bowl. The core is arranged at a second radial position that is outboard from the entryway to the effluent tube and includes one or more core passageways for providing fluid communication between the primary and secondary separation chambers. A sealed region is formed at the upper edge of the core relative to its attachment point to the bowl body. Also provided is a method for recovering a whole blood fraction from a donor using the core of the present invention.
