Abstract
The disclosure is of an improved method and apparatus for separating blood into light, substantially liquid phase and its heavy, substantially cellular phase by centrifuging a blood filled container having disposed therein an inert, gel-like barrier material possessing a density intermediate between the two phases of the blood. The improvement comprises employing a constricted tubular container, the constriction being at the zone where it is calculated the gel-like barrier material will align during centrifugation.
