Agilent 1260 Infinity Binary Pump (G1312B) (Refurbished)

The Agilent 1260 Infinity Binary Pump (G1312B) is part of the Agilent 1260 Infinity Binary LC system, designed for high-performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography (UHPLC) applications. This pump supports a wide range of chromatographic techniques by delivering unparalleled precision and reliability in flow rates, gradient formation, and pressure control. Its design incorporates advanced features for low delay volumes and minimal peak dispersion, ensuring compatibility with both conventional and modern chromatographic methods.

Key highlights include its dual-piston in-series pump mechanism for stable flow delivery, a configurable flow rate from 0.05 to 5 mL/min at pressures up to 600 bar, and compatibility with both degassed and standard solvent systems. The G1312B is optimized for robust, high-throughput applications while maintaining exceptional separation resolution.
