An instrument, consisting of a barrel and a tight-fitting piston with a connecting rod, used to inject or withdraw fluid. The barrel is usually calibrated in fluid units and the nozzle is shaped to fit a standard range of needles. Luer-lock syringes are designed so that the needle cannot be forced off by high pressure. Most modern syringes are plastic and disposable and are pre-sterilized and supplied in sealed containers.
