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.

Centrifugal elutriator rotor

A large diameter air driven centrifuge rotor which holds a plurality of centrifuge tubes in a fixed horizontal position. The rotor is designed to operate in a stable and smooth condition on a rotor seat which is smaller than the diameter of the rotor. Although the rotor essentially covers the rotor seat portion of the centrifuge, the rotor is designed in such a manner that the air flow from the driving air being exerted on the rotor will properly exit from between the rotor and the seat without affecting a stable smooth operation of the rotor.
