A dual centrifuge () embodies the following: a driveshaft (), a rotor (), which is mounted on the driveshaft () and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (); an opening () in the rotor (), wherein an end region () of the driveshaft () at least engages into said opening; and an additional drive mechanism () for the rotational unit or the rotational units (). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor () can be arranged on the driveshaft () at all times. The various rotor types () are also adapted to the additional drive mechanism () for the rotational units () such that the function is not adversely affected. A design for operating at least one angular head rotor () and a swing-out rotor (). For this purpose, the driveshaft () and the various rotor types () are adapted to each other. The bearing (), the driveshaft (), and the various rotor types () are adapted to one another such that each non-dual rotor () has a geometry that is measured such that when the rotor () is mounted, a drive device () of the additional drive mechanism () for the rotational units () is arranged so as to not contact the mounted rotor ().

Centrifuge with exchangeable rotors

A rotor () of a dual centrifuge which can be rotated about a drive axis (A) in a centrifuge, which rotor comprises at least two rotary units () that are arranged symmetrically to one another and have a bearing () and a rotary head () which is connected to the bearing () and which is mounted in the bearing () so as to be rotatable about a rotational axis (R, R), which rotary head () can be driven about the rotational axis (R, R) relative to the rotor by another rotary mechanism () of the centrifuge and has a rotary head receiving unit () for at least one sample container or at least one sample container receptacle (), with the rotational axis (R, R) of the rotary head () being inclined relative to the drive axis (A) of the rotor, the rotary head receiving unit () being designed to receive an elongated sample container receptacle () or an elongated sample container, and the longitudinal axis of the sample container receptacle () introduced into the rotary head receiving unit () or the longitudinal axis of the sample container introduced into the rotary head receiving unit () extending perpendicular to the axis of rotation (R, R) of the rotary head () or being oriented at an angle ranging between more than 0&#xb0; and less than 90&#xb0; relative to the axis of rotation. At least one connection region () is provided to which at least one damping mass () can be selectively attached either in a releasable manner or, by a fixing element, in a permanent manner for operation.
