| 摘要 |
The invention relates to a pipette device having a pipette unit (1), a positioning unit (4), a micro-dosing unit (5) and a control device (6). The micro-dosing unit (5) is implemented separately from the pipette unit (1). However, it can be coupled to the pipette unit (1) in a precisely defined relative position. The pipette unit (1) thus has a coupling device (10) and the micro-dosing unit (5) has a corresponding counter-coupling device (11). One of the two devices can be switched. By switching the coupling device (10) and/or the counter-coupling device (11), the micro-dosing unit (5) can be coupled to the pipette unit (1) or decoupled from the pipette unit (1) as desired. If the micro-dosing unit (5) is coupled to the pipette unit (1), it can be moved to different operating positions together with the pipette unit (1). |
