Waters 626 Pump

This used Waters 626 Pump is a gradient solvent delivery pump engineered for precise multi-solvent blending in high performance liquid chromatography systems. It was designed to deliver accurate flow and composition control across a broad flow rate range, supporting both routine and complex gradient methods. As a used unit, it has previously operated in an active laboratory setting and is offered here for continued service in a compatible HPLC configuration. The 626 Pump was commonly used as part of the Waters 600 series HPLC systems, working alongside system controllers, detectors, and autosamplers to deliver full analytical chromatography workflows. Laboratories in pharmaceutical development, environmental testing, and academic research have relied on this pump for its consistent performance in gradient elution applications. Its compatibility with established Waters system architecture makes it an attractive option for labs maintaining legacy equipment or building out additional HPLC capacity. This listing offers a functional, previously used pump ready to be reintegrated into a working chromatography line. It represents a practical, cost conscious way to add or restore gradient pumping capability to an HPLC bench.
