ABSTRACT:
A centrifuge rotor is characterized by a pair of magnetically attractive segments which are located between a clamping knob on an axially extending mounting bolt and the body of the rotor. The bolt holds the rotor to a drive spindle with a predetermined clamping force. As the rotor is rotated past a predetermined rotational speed the attractive force between the segments is overcome to cause the segments to displace apart thereby diminishing the magnitude of the clamping force holding the rotor in its connection to the drive spindle.
