An automated, continuous flow blood cell separator has been developed by the National Cancer Institute and International Business Machines Corporation.

Development of the separator, which can process up to 100 ml of blood per minute, was announced at the 15th annual Research Equipment Exhibit and Instrument Symposium in Washington, DC.

The machine makes possible the separation and isolation of comparatively large yields of platelets and lymphocytes with an ease and rapidity heretofore unattainable, according to its developers.

With further refinement, it may also be possible to extract significant amounts of granulocytes, Seymour Perry, MD, chief of the NCI Medicine Branch, told the Symposium.

The separator can be used for bulk processing of bank blood; or, with incorporation of certain monitoring devices, for the immediate processing of blood from donors. The machine extracts the blood, separates it into fractions and returns the plasma and, if desired, the erythrocyte fraction to the
