Apparatus for the automatic introduction of a pipetting insert through the stopper of a sample vessel sealed by the stopper and containing a sample. To ensure complete introduction of the pipetting insert into the stopper, the apparatus is characterized in that it comprises the following components: (a) an entry device which receives successively individual sample vessels sealed by a stopper, and positions the same in a predetermined position, (b) a feed device which successively brings individual pipetting inserts to a delivery station, (c) a press-in device which is movable by a drive device and which comprises a plunger and guides the plunger so that it takes a pipetting insert from the delivery station of the feed device and presses it against the stopper of the sample vessel and thus introduces it at least partially into the stopper. (d) a percussion device which is contained in the press-in means and by which, after at least partial introduction of the pipetting insert into the stopper, it is possible to apply at least one impact by the plunger to the pipetting insert, and (e) a control device for controlling all the above devices.
