Abstract
A centrifuge hub-rotor drive is disclosed in which a rotor has an internal recess that fits over and interfaces with a hub. The hub has a skirt with a curved outer periphery that interfaces and contacts internal walls of the rotor which define a tapered section of the recess. The curved outer periphery of the skirt ideally meets the internal tapered walls of the rotor along a curved contact band. The outer periphery of the skirt is taken from a portion of a spheroid, regular, oblate or prolate.
