Abstract
A device for processing donated blood comprises a porous medium interposed between the collection bag and a satellite bag into which a component separated by centrifugation can be expressed, the filter element preferably having a CWST of about 70 to about 115 dynes/cm. The porous medium blocks red blood cells, but allows platelets to pass therethrough.
