Agilent 1290 Infinity II G7120A High Speed Pump

The Agilent 1290 Infinity II G7120A High Speed Pump is a binary solvent delivery unit engineered for ultra high pressure liquid chromatography, offered here in used working condition. Built to deliver precise, pulse free flow at pressures suited to sub two micron column particles, it forms the solvent delivery backbone of modern UHPLC systems used for fast, high resolution separations. Its design targets labs that need short run times without sacrificing chromatographic performance. This pump is commonly used in pharmaceutical quality control, contract analytical testing, and research laboratories running rapid method screening or high throughput sample queues. It is built to work seamlessly with other 1290 Infinity II modules including autosamplers, column compartments, and detectors, letting a lab reconfigure or scale an existing UHPLC train around a dependable pumping module. The high speed design also supports gradient methods where fast equilibration between injections is important for productivity. As a pre-owned unit pulled from active laboratory use, this pump is a cost effective way to add UHPLC capacity, replace an aging solvent delivery module, or build a second system from spare parts already on hand. Buyers should plan for standard performance verification and seal inspection before returning the pump to production analysis.
