An impregnated porous disc made of an inert material with voids adapted for insertion into a collection tube containing clotted blood which disc upon centrifugation of the tube will allow separation of fibrin and cellular material from the serum by centrifugal force during its controlled descent through the serum and will stop when it hits the serum-clot interface to isolate the serum from the clot.

A separation device for insertion into a tubular container for isolating the lighter components from the heavier components of blood mixtures selected from coagulated whole blood and mixtures of whole blood with anti-coagulants comprising: a cylindrical disc made of an inert porous polymeric mateRia

A separation device for insertion into a tubular container for isolating the lighter components from the heavier components of blood mixtures selected from coagulated whole blood and mixtures of whole blood with anti-coagulants comprising: a cylindrical disc made of an inert porous polymeric mateRial having a pore size of about 70 to 300 microns, the said disc having a diameter sized to form a sliding fit with the inner wall of the tubular container and a height sized to maintain the disk coaxial with respect to the tubular container; said disc being coated with a hydrophobic material to make the surfaces of the porous material of the disc hydrophobic to increase the descent time of the disc through the soluble components; said coated disc having a specific gravity such that it will sink in said lighter components but will not sink in said heavier components.
