ABSTRACT:
A blood collection assembly and closure therefor, for the collection, separation, isolation and storage of serum from blood. The closure is constructed of a cannula penetrable self-sealing elastomer and includes a thixotropic barrier material in a hollow central portion of the closure, so that the barrier material is sealed within the closure until blood has been collected in the collection container and centrifuged. Centrifugation forces the barrier material into a collecton container through the passageway created by the cannula.
