Abstract
Apparatus and a method are described, wherein a coagulator accelerator is added to a container to achieve agglutination of blood cells when centrifuging whole blood, allowing the serum to be more easily poured off. The accelerator is selected from polymeric amines that are either polymerized amino acids or vinyl addition polymer amines, with a specified molecular weight range, the vinyl addition amines being selected to avoid lysing the blood cells.
