Abstract
A centrifuge structure for automatically separating a plurality of aliquot samples of blood plasma for testing from an initial sample of whole blood. A centrifuge bowl is provided with a bottom surface sloping upwardly and outwardly and joined to a vertical circular outer wall. A plurality of radially extending vertical septa or partitions divide the outer portion of the bowl into a plurality of radially extending chambers. Each of these chambers is provided with an exit port in the bottom surface. Whole blood placed in the bowl is forced radially outward by the centrifugal action of the bowl when rotated, and separates into different fractions. The selected fractions are moved to the vicinity of the exit ports by selectively changing the rotational velocity of the centrifuge and are then valved to other containers by opening valves connected to the exit ports.
