The customizable Binary Gradient Pumping System is an advanced pumping system for two-solvent high-pressure gradient applications. The system is designed with two single-head positive displacement piston pumps integrated into a functional enclosure. Equipped with belt drive pump mechanisms with shaped cam and electronic fast refill, the system produces very low pulsation. 

The included Gradient Board allows for autonomous binary gradient formation without the need for continuous computer monitoring and control. Serial commands may be used to directly set pump flow rates, start/pause, or monitor status. Additional features include control of two solvent-selection valves, multiple timed events, and leak detection.
