Claim Text:
1. A pipetting device for pipetting at least one fluid laboratory sample into at least one pipetting vessel, said pipetting device comprising: a main body extending along an axis direction; at least one connecting section, configured to be connected to the at least one pipetting vessel by an at least partially axial connecting movement along a positive axis direction; wherein the at least one connecting section is connected to the main body so as to be movable at least parallel to the axis direction; and wherein the at least one connecting section is configured such that, by way of the connecting movement, at least one complementary connecting section of the at least one pipetting vessel is plugged into the at least one connecting section is fixed there by clamping; a spring mechanism, by which the at least one connecting section is supported with spring loading on the main body at least in a first operating state of the pipetting device, such that the at least one connecting section, during the connecting movement, is capable of performing a spring-assisted deflection movement along the positive axis direction; characterized the main body of the pipetting device comprises a stop and is a configured such that, in the first operating state, the deflection movement is performed between a start position and an end position, and at the end position of the deflection movement, the stop is abutted by an upper edge of the at least one pipetting vessel connected to the connecting section, and wherein an auxiliary mechanism is provided on the pipetting device and is configured to act on a deflection movement of the at least one connecting section in at least a second operating state of the pipetting device; and wherein the pipetting device is configured such that the pipetting device is capable of being alternately put into the first operating state or the second operating state.
