The Agilent Technologies 1260 Infinity Isocratic Pump (G1310B) is a high-performance isocratic HPLC pump providing precise control of mobile phase flow. Its design incorporates two pistons arranged in series, with a servo-controlled variable stroke mechanism. This configuration delivers stable solvent flow with high precision and reduced pressure pulsation.
The G1310B operates over a flow range of 0.2–10.0 mL/min and supports operating pressures up to 600 bar. It offers user-adjustable compressibility compensation, diagnostic functions, and leak detection. The Early Maintenance Feedback (EMF) system supports instrument usage monitoring and maintenance planning. The pump is designed for isocratic HPLC analysis, where the mobile phase composition remains constant throughout the separation.
