Title: Continuous flow fractionation and separation device and method

Abstract: A centrifuge apparatus is provided for separating red blood cells and other dense solids from a suspending liquid. An enclosure means encloses liquid suspended red blood cells and is rotatable about its axis. An injector means moves the liquid suspended blood cells into and the separated blood cells out of the enclosure means and a seal means seals the injector means to the enclosure means in a liquid-tight relationship. A plurality of red blood cells receiving means are spaced about the periphery of the enclosure means and are serially connected by ducts. Suspending liquid, passing from receiving means to receiving means, will be at least partially depleted of red blood cells after passing through each receiving means. An intake passage moves liquid suspended red blood cells from the injector means into the first red blood cell receiving means and a discharge passage passes essentially blood cell-free suspending liquid from the last blood cell receiving means to the injector means and into an external receptacle.
