Harvard Apparatus 22 Syringe Pump

Cambridge Scientific ID #'s: 13820, 18357, 13819

Description:

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. A number of special features result from use of microprocessor technology.
