Abstract:
A centrifugal method of separating and collecting components from a fluid, comprising:providing a centrifuge operable at a plurality of rotation speeds and having a mounting assembly for positioning and retaining a disposable separation assembly relative to the centrifuge at the rotation speeds; mounting the separation assembly comprising a number of collection chambers in the mounting assembly, wherein each of the collection chambers include an outer collection portion with a port for providing a fluid pathway for the fluid into and out of the collection chambers and wherein the mounting includes fluidically connecting the ports with a fluid tube; connecting a fluid source to the fluid tube; rotating the centrifuge at a fill speed less than about 1000 rpm; operating the fluid source to supply the fluid to the fluid tube, whereby the fluid is concurrently supplied in substantially equal volumetric and component density quantities to each of the collection chambers and then rotating the centrifuge at one or more faster speeds to separate components of the fluid.
