Abstract
An assembly for transferring rotation from a centrifuge drive system to a centrifuge rotor includes a hub that is connected to the drive system for rotation about an axis. A sleeve member is attached to the hub in a position to support the centrifuge rotor. The sleeve member is formed of a material having a low coefficient of friction and is positioned to reduce the likelihood of rotor-to-hub lock. The resistance of the sleeve member to wear and to the absorption of foreign matter are also important in the selection of a material for forming the sleeve member. An acetal-based compound is preferred. By connecting the sleeve member to the hub such that the exterior surface of the sleeve member is raised relative to the surface of the hub, rotor-to-hub contact is reduced, thereby further reducing the risk that the rotor and the hub will become locked to one another.
