Pipetting device for an apparatus for processing a sample or reagent, apparatus for processing a sample or reagent and method for pipetting a sample or reagent

A pipetting device (100) for an apparatus for processing a sample or reagent is disclosed. The pipetting device (100) comprises a coupling mechanism, wherein the coupling mechanism comprises at leasta first coupling unit (104) adapted to be coupled to a first pipetting tip (108) and a second coupling unit (106) adapted to be coupled to a second pipetting tip (110), and a selection element (138) for selectively allowing a coupling of the first coupling unit (104) to or releasing the first coupling unit (104) from the first pipetting tip (108) and for selectively allowing a coupling of the second coupling unit to or releasing the second coupling unit (106) from the second pipetting tip (110). The selection element (138) is mechanically coupled to the first coupling unit (104) and the secondcoupling unit (106). Further, an apparatus (198) for processing a sample or reagent and a method for pipetting a sample or reagent are disclosed. 公开了用于处理样品或试剂的设备的移液装置(100)。所述移液装置(100)包括耦合机构和选择元件(138)，其中所述耦合机构至少包括适配为耦合于第移液头(10
