Abstract
A device for locking a volume adjustment screw for a pipetting system, comprising a control member which rotates as one with a position selector, the member cooperating with a locking wheel such that: when the selector is in the free adjustment position, the member ensures that the wheel is axially spaced from another wheel, such that the teeth of the wheels do not cooperate with each other; when the selector is in the fine adjustment position, the member allows the wheel to move away from and then to move axially towards the other wheel while transitioning from one tooth to another; when the selector is in the locking position, the member axially locks the wheel to prevent the teeth from being disengaged.
