The Agilent 1200 Infinity Binary Pump (G1312B) is a high-pressure binary solvent delivery module for HPLC and UHPLC separations. It combines two independent pumping channels with high-pressure solvent mixing and delivers flow rates up to 5 mL/min at pressures up to 600 bar. Its dual-piston-in-series design, active inlet valves, and solvent compressibility compensation provide accurate mobile-phase delivery and stable chromatographic performance.
