Abstract
A cover having a free-turning knob in its center for use on the rotor of a centrifuge. The knob includes tool means for coupling the knob with a threaded fastener securing the rotor to a drive shaft. Thus, when the cover is positioned on the rotor, the threaded fastener securing the rotor can be tightened or loosened by a turning of the knob. The rotor can thereby be removed and replaced without the use of external tools.
