Patent attributes
The invention relates to a pipetting device for pipetting at least one fluid laboratory sample into at least one pipetting vessel, said device having a main body extending along an axis direction, at least one connecting section, to which at least one pipetting vessel can be connected by an at least partially axial connecting movement along the positive axis direction, wherein the at least one connecting section is connected to the main body so as to be movable at least in the axis direction, 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, can perform a spring-assisted deflection movement along the positive axis direction, wherein an auxiliary mechanism is provided on the pipetting device and is designed to act on the deflection movement of the at least one connecting section in at least a second operating state of the pipetting device, wherein the pipetting device is designed such that the user can alternately put it into the first operating state or the second operating state. The invention further relates to a multi-channel pipetting device.
