ABSTRACT:
A centrifuge with variable angle of attack or positioning angle containing pivotable holders for centrifuge tubes or the like which contain a sample. At the centrifuge rotor there are arranged stops for limiting the outward pivoting of the holders. The position of the stops is variable. The stops are preferably assembled together into a ring which is displaceable and fixable in position at the rotor. The stops optionally can also be merely assembled together into groups. The ring can be structured at its lower part so as to have a sawtooth-shape or with steps. By means of a scale there can be indicated the position of the stops. The centrifuge preferably is employed for separating erythrocytes in a blood sample, and generally can be used for separating particles suspended in a liquid.
