A multivolume pipette (1) is provided. In an exemplary embodiment, the multivolume pipette includes a pipette body (50), a piston (3) disposed within the pipette body, a first chamber (7), a second chamber (8), and a valve F(13). The first chamber and the second chamber are defined at least in part by an inner wall (52) of the pipette body and the piston. The valve is capable of placing the second chamber in fluid communication with an external environment to provide a first volume range of the multivolume pipette. The valve is also capable of placing the second chamber in fluid communication with the first chamber to provide a second volume range of the multivolume pipette.
