Abstract
In a centrifuge rotor assembly, a self-retaining rotor lid which is designed to stay on the rotor even when the lid is not tied down or secured to the rotor. The lid has a lip formed on an outer edge of the major side of the lid that faces the open end of the rotor body. The height of the lip is such that the lip extends beyond the edge of the open end of the rotor body. The lip has a diameter that is nominally smaller than the diameter of the open end of the rotor body, thus establishing a clearance therebetween. The clearance allows easy engagement of the lid to the rotor body, but is small enough to prevent the lid from tilting, which keeps the lid on the rotor even when the lid is not secured during centrifugation.
