Apparatus for the homogenization and separation of samples

An apparatus for the homogenization and separation of media (10) comprising a centrifuge (40, 70) having a centrifuge rotor (14, 44, 74) which can be rotated about a motor axis (A) of a centrifuge motor (12, 42, 72) and which includes a rotor body, connected to which is at least one rotation unit (16, 48, 80) in such a way that it is additionally adapted to be rotatable about an axis of rotation of a rotation unit which is different from the motor axis (A), and that it can be driven via a rotation unit drive, with means being provided which can be used to set at least two different rotation speeds of the rotation unit (16, 48, 80), and furthermore the rotation unit (16, 48, 80) has toothing (8) on its periphery by which the rotation unit (16, 48, 80) can be driven, said at least one rotation unit motor (76) which is independent of the centrifuge motor (12, 42, 72) is provided as the rotation unit drive and is mounted on the centrifuge rotor.
