Abstract
This invention proposes an improved portable and disposable centrifugal apparatus having a centrifugal processing chamber (13) of variable dimensions that can process a variable quantity of biological fluid, even down to very small quantities, by displacement of an axially movable member such as a piston (5). The invention also concerns the overall centrifugal apparatus and instrumentation cooperating with the processing chamber (13), a disposable set comprising the processing chamber (13) and a set of collection bags, as well as methods of processing biological fluids in this apparatus, in particular the collection and separation of whole blood.
