Abstract: The invention relates to a syringe having a longitudinal axis and comprising a barrel assembly including a barrel extending longitudinally between a proximal end and a distal end, and a collar provided at the proximal end of the barrel and defining a reading window. The syringe also comprises a plunger including a longitudinally extending graduation portion that is at least partially longitudinally slidably received in the barrel, and that provides for at least two mutually different visually readable graduations, wherein respective graduations extend along the longitudinal axis and are alternatively selectable by rotation of the graduation portion around the longitudinal axis, such that a selected graduation is visible through the reading window when the plunger is slid into and out of the barrel during use.
