The Agilent Technologies 1260 Infinity Isocratic Pump (G1310B) is an isocratic HPLC pump designed for precise and stable mobile phase delivery. It features a dual-piston, in-series pumping system with a servo-controlled variable stroke drive. This design provides consistent solvent flow, high precision, and low pressure pulsation.
The pump offers a flow range of 0.2–10.0 mL/min and supports operating pressures up to 600 bar. Its features include adjustable mobile phase compressibility compensation, integrated diagnostics, and leak detection. The Early Maintenance Feedback (EMF) function helps monitor instrument usage and plan maintenance activities. The G1310B is suitable for isocratic HPLC separations requiring a constant mobile phase composition.
