RAN 4090/213 Abstract Apparatus for the automatic introduction of a pipetting insert (11) through the stopper (14) of a sample vessel (13) sealed by said stopper (14) andcontaining a sample. To ensure complete introduction of the pipetting insert (11) into the stopper, the apparatus is characterized in that it comprises the following components: (a) an entry device (51) which receives successively individual sample vessels (13) sealed by a stopper (14), and positions the same in a predetermined position, (b) a feed means (52) which successively brings individual pipetting inserts (11) to a delivery station (53), (c) a press-in means (55) which is movable by a drive means (54) and which comprises a plunger (41) and so guides the same that it takes a pipetting insert (11) from the delivery station of the feed means (52) and presses it against the stopper (14) of the sample vessel (13) and thus introduces it at least partially into the stopper, (d) a percussion means (42, 43) which is contained in the press-in means (55) and by means of which, after at least partial introduction of the pipetting insert (11) into the stopper (14), it is possible to apply at least one impact by the plunger (41) to the pipetting insert (11), and (e) a control means for controlling all the above means.
