A system for separating components from a composite fluid, the system comprising: a centrifuge ; a plurality of separation units (116A-F; 200; 500; 600) positioned in the centrifuge, each of the separation units comprising: a first chamber (216; 516; 616) comprising a first expressor (224; 524; 624); a second chamber (220; 520; 620) positioned closer to an axis of rotation (204; 504; 604) than the first chamber; a third chamber (212; 512; 612); a first valve (240; 540; 640) controlling flow from the first chamber; and a second valve (244; 544; 628) controlling flow from the second chamber a memory storing processor executable instructions that when executed perform a method comprising: spinning the centrifuge at a first speed to separate a composite fluid into at least a first component, a second component, and a third component; transferring at least a portion of the first component and the second component from the first chamber to the second chamber using the first expressor; spinning the centrifuge at a second speed; and transferring a second portion of the first component out of the second chamber; and transferring a third portion of the first component out of the first chamber using the first expressor. a centrifuge ; a plurality of separation units (116A-F; 200; 500; 600) positioned in the centrifuge, each of the separation units comprising: a first chamber (216; 516; 616) comprising a first expressor (224; 524; 624); a second chamber (220; 520; 620) positioned closer to an axis of rotation (204; 504; 604) than the first chamber; a third chamber (212; 512; 612); a first valve (240; 540; 640) controlling flow from the first chamber; and a second valve (244; 544; 628) controlling flow from the second chamber a first chamber (216; 516; 616) comprising a first expressor (224; 524; 624); a second chamber (220; 520; 620) positioned closer to an axis of rotation (204; 504; 604) than the first chamber; a third chamber (212; 512; 612); a first valve (240; 540; 640) controlling flow from the first chamber; and a second valve (244; 544; 628) controlling flow from the second chamber a memory storing processor executable instructions that when executed perform a method comprising: spinning the centrifuge at a first speed to separate a composite fluid into at least a first component, a second component, and a third component; transferring at least a portion of the first component and the second component from the first chamber to the second chamber using the first expressor; spinning the centrifuge at a second speed; and transferring a second portion of the first component out of the second chamber; and transferring a third portion of the first component out of the first chamber using the first expressor. spinning the centrifuge at a first speed to separate a composite fluid into at least a first component, a second component, and a third component; transferring at least a portion of the first component and the second component from the first chamber to the second chamber using the first expressor; spinning the centrifuge at a second speed; and transferring a second portion of the first component out of the second chamber; and transferring a third portion of the first component out of the first chamber using the first expressor. <EOS>
