Hewlett Packard HP 1100 Series G1312A Binary Pump for HPLC, Made in USA, Tested

Serial: YUS53700119

The Hewlett Packard HP Agilent 1100 Series G1312A Binary Pump is a high-precision liquid chromatography pump engineered for both gradient and isocratic HPLC applications. Featuring dual pistons in series, a floating piston design, and active inlet valves, it delivers accurate and stable flow from as low as 0.001 mL/min up to 5.0 mL/min. It includes user-selectable compressibility compensation to optimize performance for different solvent systems, minimal pulsation even under high pressures, and robust materials that tolerate a wide pH range. With features such as early maintenance feedback (EMF) and electronic error diagnostics, it is well suited for demanding analytical workflows where reproducibility, durability, and reliability are critical.
