Abstract
The invention relates to a device for holding a pipette in a pipetting aid, permitting gastight insertion of the pipette into the pipetting aid without contact pressure having to be exerted by the person handling it, spreader elements (2) being cast in a soft rubber or plastic aperture bead of the pipetting aid, and it being possible for the spreader elements (2) to have their positions relative to each other changed by tensioning elements (3) in such a way that the aperture bead can be widened for the insertion of the pipette.
