Abstract
This invention relates to an improvement in two-port centrifuge bowls in which component yield is enhanced by utilizing the centrifuge bowl for eluttriation, as well as centrifugation. In a particular embodiment, platelet yield is improved by terminating flow of anticoagulated whole blood from the donor to the bowl and pumping low density fluid, preferably plasma, back into the bowl at a relatively high rate to elutriate centrifugally separated cells in the bowl.
