摘要

The disclosure is of a method and apparatus for the separation and isolation of the separated plasma or serum phase of a blood specimen. The method comprises the in situ formation of a barrier between the separated lighter plasma or serum phase and the heavier cellular phase of the blood specimen, accomplished by centrifugation. The barrier comprises beads of certain specific gravity, which are coated with an adhesive. The apparatus employed comprises a conventional vacuum container having the barrier component located in a position adjacent to or within a closure member of the container.
