<p>A centrifuge rotor lid (44) assembly which includes a handle (64) which allows convenient handling of a centrifuge rotor (30) and provides a means of releasing the lid (44) from the rotor (30) after centrifugation. In the described embodiment, the lid (44) is provided with a lid knob (48) and a spindle knob (50) in a coaxial sliding arrangement. The lid knob (48) is used to tighten the lid (44) on the rotor body (30) and the spindle knob (50) is used to tighten the rotor (30) to the centrifuge drive spindle (36). The upper end of the inner knob (50) is provided with a handle (64) which extends perpendicular to the axis of the knob. This handle (64) is used for lifting the rotor (30) after the spindle knob (50) has been unscrewed from the spindle (36) and for unscrewing the lid knob (48). The lower end of the spindle knob (50) has a pin (66) which cooperatively engages the lower end of the lid knob (48) when the spindle knob (50) is lifted from the rotor (30) and is turned in a direction to unscrew the lid knob (48). The handle provides the necessary mechanical advantage for a person to exert sufficient torque to unscrew the lid knob (48) without the use of external tools.</p> |
