Abstract
A cell washing method and apparatus which utilizes centrifugation to separate blood components in a flexible bag. The less dense separated components e.g., supernatant, is expressed from the bag by centrifugal force acting on a plate adjacent the bag and the more dense component e.g., RBC's, remains. The bag is oriented at a double angle in the centrifuge so that less dense component accumulates at one location and more dense at a second location diagonally opposite the first location, thus facilitating removal of the less dense and washing of the more dense component.
