<p>A method and apparatus for concentrating red blood cells and washing said cells to remove supernatant is described wherein blood is centrifuged in a core-less integral centrifuge bowl at a predetermined speed to pack the more dense red cells leaving a toroidal layer of less dense supernatant. Cell washing fluid displaces the supernatant from the bowl. A mixing cycle is established wherein the centrifuge is slowed down to mix the washing fluid and red cells. The centrifuge is then returned to speed and further washing fluid is introduced. The mixing cycle is successively repeated until a satisfactory washout is established.</p> |
