ABSTRACT:
Methods and apparatus for separating blood which utilize suspendable contact-activating particles to initiate blood clotting generally throughout the volume of blood are disclosed herein. The contact-activating particles are deposited in a vessel; and when whole blood is supplied to the vessel, the particles are suspended throughout the volume of the blood and remain so suspended, without mechanical agitation, during at least the initial stages of coagulation. The particles are precipitated from the serum portion of the blood during a subsequent centrifugal separation. Also, a process for making appropriately sized contact-activating particles is disclosed.
