ABSTRACT:
The present invention relates to a fixing device of a cover for a centrifuge rotor, a receiving chamber of the centrifuge rotor, which is driven using a drive unit, for receiving samples to be centrifuged being closable aerosol-tight using the cover. The fixing device is provided with an opening so that the drive unit is accessible through the fixing device and the cover without removing the cover. The present invention has the advantage that the rotor may be removed from the centrifuge and the rotor remains closed aerosol-tight at the same time. In addition, simple, one-handed operation is made possible.
