Abstract
In order to improve the ergonomics of a sampling pipette, the invention provides a control member intended to occupy a nominal central position in which a spring brings a locking member into the locking position thereof of the system for adjustment of the volume to be sampled, the member being able to be axially displaced towards each of the two following positions: a low position for ejecting a cone, in which the control member presses on the cone ejector, the movement from the nominal central position to the low position being carried out against the springs; and a high position for unlocking the braking ring, the movement of the control member from the nominal central position to the high position driving a disengagement element to move the locking member against the spring, until release of the braking ring.
