ABSTRACT:
This invention relates to a method and apparatus for the separation of finely divided solid particles dissimilar in size and/or density, such as platelets and other blood cells. The separation of, for instance, platelets is accomplished by subjecting the blood sample to centrifugal force in the chamber while displacing the platelets from the blood sample by injecting a relatively small volume of saline into the centrifugally outer end of the chamber. In the preferred apparatus, the saline is injected into che blood sample by driving the chamber supporting the blood sample into a saline filled cavity under the influence of centrifugal force.
