Abstract:
1. A pipetting device, comprising a base plate; a plurality of pipetting channels are arranged in a defined grid in said base plate; a magazine populated with pipette tips in said grid, each of said tips having a tip shoulder; a magazine holder; a drive motor; and a gear mechanism, which connects said magazine holder and said drive motor, so that said magazine is movable vertically between an aspirating and dispensing position and a sealing position, in which the tip shoulders are non-positively connected to said pipetting channels in such a way that said tip shoulders and pipetting channels are sealed off from each other, wherein said magazine holder is in an open state when in the aspirating and dispensing position, so as to form a passage opening larger than the magazine, so that the magazine can be inserted into the magazine holder from the bottom; and wherein the magazine holder is in a closed state when in the sealing position, in which the support surfaces, against which the magazine rests, project into the passage opening; and wherein said gear mechanism is designed in such a way that when it is driven, not only is the magazine moved vertically, but also the magazine holder is moved into the said aspirating, dispensing and sealing positions.
