Abstract
The method of rapidly separating plasma or serum from red blood cells comprising the steps of mounting a pair of spaced apart tubes coaxially related to one another head-to-head with a sharp-ended hollow needle disposed generally along the tube axes and between them, arranging the tubes in a vertical position one above the other in a centrifuge with the tubes closed with self-sealing stoppers, providing a partial vacuum in the upper tube, rotating the tubes at high speed about an axis parallel to and spaced from the axis of the tubes and needle, after separation of the red blood cells from the plasma and serum causing the tubes while still being rotated to be moved relative to one another such as to cause the needle to enter both tubes through the stoppers, separating the tubes while still being rotated by the centrifuge whereby to remove the needle from both tubes.
