Abstract

A multiple-sample centrifugal rotor for blood fraction preparation is described. The rotor assembly includes an inner disk-shaped portion defining a circular array of whole blood sample-receiving chambers. Blood samples are statically loaded into the respective chambers through static loading ports. Liquids for washing and hemolyzing the cell fractions are introduced to the chambers following recovery of the plasma fraction by means of a central dynamic distribution port and a multiplicity of distribution passageways extending between the dynamic distribution port and the centrifugal ends of respective chambers. Unloading of blood fractions and washing liquid is accomplished through transfer passageways extending from a point intermediate the centrifugal and centripetal ends of the chambers radially inward and then outward to the periphery of the inner disk-shaped rotor assembly portion. A removable outer rotor portion defining at least one collection chamber for receiving materials discharged from the transfer passageways is nested concentrically about the inner rotor assembly portion.
