Abstract:
1. A rotor for a centrifuge, wherein the rotor is rotatably driven about a rotation axis has an outer circumference spaced a radial distance from the rotation axis and comprises two parts, a central bearing part and a waste collecting part which is provided with a waste collecting area, comprising: the waste collecting part being separable from the bearing part for one of waste disposal and cleaning; the bearing part and the waste collecting part being provided with torque transmitting surfaces which interact with each other in at least one of a form-fitting and adherence manner, and being connectable by axially positioning the waste collecting part on the bearing part and disconnectable by axially removing the waste collecting part from the bearing part; circumferences of the bearing part and the waste collecting part being connectable in a form-fitting manner and arranged in such a way that the waste collecting part circumference engages with the corresponding circumference of the bearing part one of in the initial state of the waste collecting part and as a result of the radial expansion thereof produced by at least one of a centrifugal force and by heating; the form-fitting circumferences being formed by annular areas; the bearing part being made of one of metal and plastic and comprising an annular area on at least one of an axially top and an axially bottom, concentric to the rotation axis; the waste collecting part being made of plastic and comprising an annular area on at least one of an axially top and an axially bottom; in a combined condition of the bearing part and the waste collecting part, the annular area of the bearing part surrounding an outside of the annular area of the waste collecting part; and the form-fitting circumferences, seen in radial direction, being arranged at a distance of no more than one half of the radial distance of the outer circumference of the rotor from the rotation axis.
