Abstract
The present invention is directed to a centrifuge rotor having a rotor body and an associated lid. A skirt with a radially outwardly facing surface thereon depends from the radially outer peripheral undersurface of the lid. A contoured cut-out is formed in at least the radially outwardly facing surface of the skirt. The undersurface of the lid radially outwardly of the skirt also has a generally contoured cut-out formed therein. The contours of the cut-out portions meld together and cooperate to define a smoothly curved concave undercut region below the periphery of the lid that accepts a lifting implement, whereby lifting or lowering of the rotor may be facilitated.
Claims11
A centrifuge rotor comprising:
- a rotor body having an axis of rotation extending therethrough, the rotor body having a radially outer peripheral portion having a generally upstanding rim thereon, an upper portion of the upstanding rim being inclined inwardly toward the axis of rotation at a predetermined angle;
- and
- a rotor lid, the lid having an undersurface thereon, the lid comprising:
- a skirt depending from the undersurface of the lid, the skirt having a radially outwardly facing surface thereon,
- the radially outwardly facing surface of the skirt having a contoured cut-out formed therein, the contoured cut-out being accessible from the exterior of the rotor for facilitating the grasping and handling of the rotor.
