This dual rate syringe pump can infuse simultaneously at different rates, or infuse with one syringe and withdraw with the other. When combined with a valve box, it provides the continuous delivery of a peristaltic or piston pump with the accuracy, absence of pulsation and low flow rates of a syringe pump. This functionality allows continuous infusion or withdrawal, 24 hours a day, 365 days a year with the accuracy and low flow of every KD Scientific syringe pump.
