Beckman Coulter 110A Liquid Chromatograph Pump

Beckman Coulter 110A Liquid Chromatograph Pump is a vintage, 115 V solvent-delivery pump built for Beckman HPLC systems, providing reliable mobile-phase flow at high pressure to drive chromatographic separations. The 110A supports gradient and isocratic operation, with a flow range from 0.1 to 9.9 mL/min and a maximum pressure rating up to 6,000 psi, enabling a wide range of analytical methods. For labs needing larger-scale separations, optional preparative heads are available that extend the flow capacity to 28.0 mL/min. Widely used as the solvent-delivery module in legacy Beckman instrumentation, the 110A pairs with Beckman detectors and controllers to deliver consistent, repeatable chromatography results in research and teaching environments. Its 115 V electrical requirement aligns with common laboratory power standards, making it a practical option for institutions maintaining older Beckman configurations. Ideal for analytical work and classroom demonstrations that rely on a proven Beckman design, the 110A remains a distinctive option when a conventional, high-pressure solvent delivery pump is required to support routine HPLC separations and method development on legacy systems.
