1. A method for sealing a cover to a rotor of a centrifuge, comprising:
biasing a plunger having an annular groove and a longitudinal axis and disposed within a housing in a first direction;
actuating the plunger in an opposite, second direction;
displacing a moveable element to at least partially enter the annular groove of the plunger;
inserting the housing into an adapter having a detent pitched at an angle relative to the longitudinal axis;
biasing the plunger in the first direction, thereby displacing the moveable element to contact the plunger and at least partially enter the detent, attaching the rotor cover to the rotor; and
rotating the housing in a third direction to urge the cover assembly to the rotor.
