The Harvard Apparatus Pump 33 is described as a highly accurate syringe pump capable of continuous fluid delivery, infusion or withdrawal, 24/7, 365 days a year
This pump provides two independent pumping channels, linked through hardware and software.
Combine the Pump 33 with a valve box (as pictured) and this pump provides continuous delivery, with the accuracy and pulse-free flow you expect of all Harvard Apparatus syringe pumps.
Modes of operation make this model a perfect fit for every lab, says the company.
Reciprocal/Parallel Mode allows the two pumping mechanisms to run completely independently - the same or opposite directions.
Proportional Mode allows different flow rates and syringe diameters to be set for each syringe holder.
AutoStop Mode terminates operation when a limit switch is activated.
Continuous Run Mode reverses direction at the flip of a limit switch.
High pressure capability, TTL, and RS-232 interface add to the Pump 33's versatility.
