Glass and disposable plastic syringes of all sizes from 1 ml to 30 ml  can be used in the Infusion pump.  The flow rates are pre-calibrated for 30 ml syringes. Using a digital thumb switch, flow rate can be  adjusted from 1 to 99 ml/ Hr.  Since it accepts other syringe sizes also, much lower flow rates can be obtained by using smaller syringe.  When the syringe is nearly empty, the pump will automatically stop with an alarm.
