Abstract
A centrifuge bowl for separating whole blood into less dense and more dense components and for collecting both less dense and more dense components without stopping bowl rotation. The fluid pathway from an inlet port to a separation chamber comprises an inlet tube and an introduction passageway. The fluid pathway from the separation chamber to an outlet port comprises a collection passageway. The introduction and collection passageways are nonrotatable. The more dense blood components can be extracted from the bowl during rotation by applying suction at the inlet port or pressure at the outlet port.
