ABSTRACT:
A centrifuge rotor locking apparatus includes a C-shaped annular member for a snap-fit engagement about a drive hub. The member comprises first and second contacting segments and a third non-contacting segment. Centrifugation causes the contacting segments to flex outwardly and come into contact with the interior wall of the drive hole of a mounted rotor. The unbalanced mass distribution of the annular member causes the member to tend to slide off the drive hub. This further separates the contacting segments, thus increasing the locking effect of the annular member/drive hub assembly to the rotor as the member is wedged in place between rotor and drive hub.
