ABSTRACT:
Apparatus for separating or partitioning different density components of a liquid includes a liquid transfer pack composed of first and second flexible bags whose interiors are connected by tubing and a carrier for supporting the transfer pack. the carrier includes first and second sections defining first and second chambers for containing said first and second bags which sections can telescope between an extended condition wherein the volume of the second chamber is a maximum and a collapsed or retracted condition wherein the volume of the second chamber is a minimum. The two sections are biased toward their extended condition so that the first and second bags can be positioned in said chambers so that when the carrier and pack are spun at a selected high speed about an axis perpendicular to the carrier telescoping axis, the carrier sections will retract thereby maintaining the second bag in a collapsed condition in the second chamber minimum volume until the spinning slows to a selected lower speed. Whereupon, the carrier sections extend so that the second chamber assumes its maximum volume allowing the second bag to extend so that the densest components of a liquid in the first bag flow into the available volume in the second bag. Specific transfer pack and carrier constructions are also disclosed.
