Abstract
A pipetting system including a positive displacement sampling pipette as well as a capillary-piston assembly, the piston of which has a top end intended to be held by a gripping device equipping the pipette, the device including a plurality of gripping tongs. The system is designed so that, when the capillary is fitted on the pipette tip and the gripping device is remote from the piston upwards, this device can be displaced downwards with its tongs in an open configuration, up to a determined position in which the tongs, arranged around the top end of the piston, automatically switch into a closed configuration in which they provide a holding of the top end of the piston.
