Abstract
A barrier device, advantageously utilized to separate blood serum from other components by centrifuging, and preferably in the form of a truncated cone having stabilizer posts extending from the conical base in the direction of truncation and an axial post extending from the opposite, concave side is disclosed. A strip of pliable material having complementary depressions therein serves as a package and dispenser for the barrier device. Insertion into a test tube is preferably accomplished by placing the test tube in the opening of the depression and ejecting the barrier device by pressure against the post through the pliable packaging material.
