Abstract
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.
