Abstract: A pipette with an adjustable volume comprises a housing comprising an outside surface, at least one seat defining an opening, and a displacement apparatus defining a displacement chamber comprising a displacement element configured to be displaced therein. A stroke rod is coupled to the displacement element and configured to be displaced relative to the housing order to displace the displacement element. An adjusting apparatus is configured to adjust a position of an upper stop in the housing, a display apparatus is configured to display a set dosing volume, and a coupling apparatus is positioned between the adjusting apparatus and the display apparatus. The coupling apparatus is configured to couple the adjusting apparatus to the display apparatus in an engaged state and configured to uncouple the adjusting apparatus from the display apparatus i.n a disengaged state.
