    Abstract: Blood serum is separated from other components of whole blood by inserting a barrier device having a specific gravity between that of the blood serum and the other blood components into a centrifuge containing a sample of whole blood, and centrifuging until the barrier device migrates to a position intermediate the blood serum and the other blood components. The preferred form of the barrier device is a truncated cone having stabilizer posts extending from the conical base parallel to the axis of the cone in the direction of truncation.
