Abstract
The present invention provides a centrifuge rotor adapted for continuous separation of specific particles from mixed populations thereof by a process of centrifugal elutriation. In the rotor, elutriation cells abut a central spindle having fluid carrying means, and thereby eliminate intermediate conduits and seals therefor, thus reducing the likelihood of leakage because of faulty aperture registration or failure of the sealing means.
