ABSTRACT:
An improved assembly for use in the centrifugal separation of serum or plasma from blood is disclosed. A tubular glass container has therein a body of gel-like material having a yield stress value such as to permit it to flow and form a transverse barrier between the separated phases of blood upon centrifugation. This container is provided with an hydrophobic inner surface portion adjacent to said barrier to enhance the adhesion of the barrier material to the container wall and inhibit leakage across the barrier of the separated blood components.
