The dual syringe Pump 33 provides two independent pumping channels, linked through hardware and software. A reciprocal/parallel mode allows the two pumping mechanisms to run completely independently – in the same or opposite directions. A proportional mode allows different flow rates and syringe diameters to be set up for each syringe holder. An auto-stop mode terminates operation when a limit switch is activated. High pressure capability, TTL, and RS-232 interface add to the pump’s versatility.
