ABSTRACT:
A centrifuge has a drive unit, a separation chamber which can be inserted into the drive unit, and a scanning device for recognizing the position of the separation chamber which is rotated by the drive unit. The separation chamber is constructed as a disposable chamber and is provided with a marker element which is arranged in a scanning region extending annularly around the rotation axis of the chamber. The position of a phase boundary window is detected by sensing the position of the marker with a phase boundary detector portion of the scanning device whereby the chamber can be inserted into the drive unit in any position.
