Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
111 words
In a high speed centrifuge having a rotor with bores for receiving sample containers, the improvement comprising: a cross-sectional contour for the bores and for the containers as received in the respective bores, the contour being defined in a plane transverse to the axis of rotation, each contour having essentially triangular configuration with three sides and three rounded corners, one corner of each bore therein pointing away from the axis of rotation and being located on a radius bisecting said one corner, the two sides of the triangle as extending from that one corner defining two load bearing faces the other two corners Being disposed symmetrically with respect to said radius.
Claim 2
Dependent Claim
