ABSTRACT:
A clamping apparatus for mechanically separating cellular elements suspended in whole blood solutions. After subjecting sealed packets of whole blood to centrifugal forces which will cause isolation of red and white blood cells, the packet is inserted within the present invention apparatus at the interface of the isolated red and white cells. A pair of parallel, spaced clamping surfaces are brought into juxtaposition with the sides of the blood packet along the cell interface causing the interior surface of the blood packet to mechanically isolate the cells along the edges of the opposed surfaces. A pair of securing arms are urged against a resilient force secured across the clamping surfaces to maintain a substantially constant force along the entire portion of the blood packet in contact with the clamping surfaces.
