ABSTRACT:
A centrifuge is provided with a mounting arrangement that secures a centrifuge bowl to a turntable in response to centrifugal force generated when the turntable is rotated. The centrifuge includes first and second retainers, one of which is connected to the turntable, while the other is connected to the centrifuge bowl. The second retainer engages the first retainer when the first and second retainers are in an interlocking position to secure the centrifuge bowl to the turntable. A movable arm is provided on the turntable and coupled to the second retainer, the movable arm has a ballast that forces the movable arm and second retainer in a first direction in response to centrifugal force generated by rotating the turntable so that the second retainer is forced into the interlocking position with the first retainer. In one embodiment, a vacuum applied to an opening in the turntable assists in mounting a centrifuge bowl to the turntable.
