HARVARD Apparatus Dual Syringe infusion pump Model 22 55-2222

The Model is an Infusion Only syringe pump employing a microprocessor controlled
small step angle stepping motor driving a lead screw and half nut. A key pad is used
for data entry of flow rate and syringe diameter. The microprocessor calculates the
cross sectional area of the syringe to be used and calibrates the flow rate for that
syringe
