HANDHEBEL FÜR ZENTRIFUGENROTOR UND DECKEL

摘要

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