Abstract
A pipette for sampling an extended range of volumes of liquid includes a fixed pipette body. An operating rod is movable in translation relative to the pipette body, along a longitudinal axis of the pipette. The pipette includes a suction chamber and a set of N concentric pistons, wherein N corresponds to an integer greater than or equal to 2. Each of the pistons contributes to delimiting the suction chamber. A coupling module couples the operating rod with the set of N concentric pistons. The module is configured in such a way as to be able to be brought into N distinct configurations in which it respectively couples the operating rod with 1, 2, . . . , N pistons.
