Agilent 1290 Infinity G4220A Binary Pump

This used Agilent 1290 Infinity G4220A Binary Pump is a high pressure solvent delivery module engineered for ultra high performance liquid chromatography work. Capable of operating at significantly higher pressures than standard HPLC pumps, this binary pump supports fast, high resolution UHPLC separations using sub-2 micron particle columns, giving labs sharper peaks and shorter run times on demanding methods. The unit has been functionally verified for flow precision and pressure stability before being made available for resale. As part of the 1290 Infinity series, this pump is built to integrate with Agilent's UHPLC modular stack and communicates over the standard system bus alongside compatible detectors, autosamplers, and column compartments. Labs performing pharmaceutical stability testing, metabolomics, or other high throughput analytical work rely on this pump's precise binary mixing and high pressure capability to achieve the resolution and speed that standard HPLC pumps cannot match. Its robust seal and check valve design is built to withstand the higher pressures inherent to UHPLC operation over extended use. Purchasing this pump used gives laboratories access to UHPLC grade solvent delivery performance at a meaningfully lower cost than new equipment, whether to restore a system to full function or expand UHPLC capacity. It is a strong option for research institutions, pharmaceutical labs, and contract testing facilities that need dependable high pressure pumping without the expense of buying new.
