Abstract
A centrifugal fluid separation system is disclosed for centrifugally separating a composite fluid into components thereof. This centrifugal separation system includes at least a centrifugal rotor which has a composite fluid containment area, a fluid flow channel/tubing and at least one separated component collection area defined therein. A composite fluid to be separated is delivered to the fluid containment area where under centrifugal forces the composite fluid is separated into components and then from which a component travels through an outlet channel to a respective separated component fluids flowing therethrough. A centrally disposed pump is also provided to move the separated component(s) to the collection area(s). Optical sensing of the interface of the separated fluid components may be used with a clamp to stop flow. A disposable bag and tubing system is also disclosed for use with reusable rotor devices.
