The Pico Plus infusion pump delivers low flow rates, either infusing or withdrawing fluid, at low to moderate back pressures. The device can hold any two syringes from 0.5 µl to 10 ml. The diameter and desired flow rate are entered via the keypad and stored in non-volatile memory. In the event of a power outage, the Pico Plus is equipped with “power failure mode” that allows the user to decide whether to turn the pump off or to resume pumping once power is restored. The pump can either operate in RATE mode, which continuously dispenses fluid at a specified rate, or the pump can release exact amounts of fluid in VOLUME mode.
