The difference between a syringe pump and a peristaltic pump

Syringe pump through the piston movement to the needle aspiration or discharge of liquid, because it is the physical distance corresponding to the volume, generally quasi-peristaltic pump. Peristaltic pump is the use of rubber hose to absorb or remove the liquid elasticity, the aging of the pipe may not be very accurate, but the pipe can be replaced, and particularly cheap, so each have their own advantages. Simply put is a syringe pumping, a hose suction.
