What is piston syringe?

A piston syringe is a medical device used to inject or withdraw fluids, consisting of a cylindrical barrel and a plunger that fits tightly within it. The plunger is moved back and forth to create suction for drawing in fluids or to push them out through a nozzle. Piston syringes are commonly used for administering medications, vaccines, or for various laboratory applications. They come in various sizes and can be single-use or reusable, depending on the design.
