A procedure for locking a pipette, the adjustment means (4) being locked with the aid of a notched circle (7) or equivalent and of a locking member (8), the notched circle or the locking member being rotatable along with the adjustment means while the other is substantially non-rotatably connected with the body of the pipette, the locking member being locked in any desired notch of the notched circle and interlocked with the adjustment means in order to prevent inadvertent rotation, and a pipette comprising a locking means (5) which has been disposed to lock and, if so desired, to release the adjustment means (4) in its direction of rotation, the locking means (5) comprising a notched circle (7) or equivalent and a locking member (8) which has been fitted to be lockable in any desired notch (9) of the notched circle for preventing inadvertent rotation of said circle and the adjustment means (4) relative to each other, the notched circle or the locking member being rotatable along with the adjustment means while the other is substantially non-rotatably connected to the body (18). |
