G7111BR, Agilent Certified Pre-owned 1260 Infinity II Quaternary Pump, maximum pressure 600 bar.

[]

The Agilent Certified Pre-Owned 1260 Infinity II Quaternary Pump is a refurbished liquid chromatography pumping module for gradient separations using up to four mobile-phase solvents. Its low-pressure mixing design combines solvent channels before the high-pressure pump, and an integrated degasser helps reduce dissolved-gas effects on delivery. This configuration has a maximum rated operating pressure of 600 bar within the appropriate flow envelope. The supplied package includes the certified pre-owned pump module with associated connecting capillaries, solvent cabinet, bottles, a column and CAN communication cable. Use the pump with compatible Agilent InfinityLab LC components and establish solvent compatibility, gradient accuracy and leak-free operation during installation qualification. When changing mobile phases, flush residual salts and incompatible solvents from the flow path to protect valves and seals. This is a certified pre-owned quaternary pump assembly, not a factory-new binary pump or a complete chromatographic system with detector and autosampler.
