ABSTRACT:
A rotor cover attach and release apparatus for a centrifuge includes a knob and a cover and housing affixed to the knob. The apparatus also includes an adapter connected to the housing and a plunger including an annular groove disposed within the knob and housing. The apparatus further includes a moveable element retained within a passage located on the housing and a biasing element located within the housing. The plunger is biased in one direction. By actuating the plunger in the opposite direction, the movable element may enter the annular groove, thereby releasing the cover from the rotor. When the plunger is not actuated, the movable element may contact the plunger and enter the passage, thereby attaching the cover to the rotor.
