Abstract

In a centrifuge including a centrifuge rotor and a drive shaft for spinning the rotor at selected rotational speeds, a safety device adapted to prevent the rotor from attaining a rotational speed likely to cause the rotor to explode with a force that could not be contained within the centrifuge housing. The device includes a safety link handle assembly supported on the top of the rotor on the rotation axis thereof having an arm designed to rupture and depart from the handle assembly at a predetermined speed thereby creating an imbalance condition of such a magnitude that the rotor separates from the drive shaft and is thereby prevented from attaining a hazardous rotational speed.
