Abstract
A blood washing system including a rotor defining an internal chamber and a skimmer assembly configured to move a withdrawal needle within the internal chamber. A multi-component fluid, such as a whole blood sample, can be fed into the internal chamber via a feed tube, where the rotor can be rotated to fractionate the multi-component fluid. A brake can be applied to the rotor to cease rotation or rotated at a slower speed to allow the fractions of the multi-component to settle on a bottom wall of the rotor. The withdrawal needle is moveable within the internal chamber to align an orifice of the withdrawal needle for withdrawing the liquid fractions and isolate the solid fractions. Wash fluids can be added to the internal chamber to repeat the wash cycle without removing the solid fractions. The washed solid fractions can be withdrawn via the feed tube and collected.
