Agilent 1100 Series G1312A Binary Pump

This Agilent 1100 Series G1312A Binary Pump is a used HPLC solvent delivery module sold in tested, functional condition following removal from a working chromatography system. It combines two solvent streams at high pressure with precise proportioning, supporting demanding gradient methods that require tight retention time reproducibility and low baseline noise. The unit fits directly into 1100 series HPLC stacks and other compatible Agilent configurations. Binary pumps are favored in labs running high resolution gradient separations where accurate, low-pulsation solvent delivery directly affects peak shape and quantitation accuracy. This G1312A pump supports pharmaceutical analysis, environmental testing, and research applications that depend on consistent gradient performance run after run, and its dual-piston design is built to handle sustained daily use in a busy analytical lab. As a pre-owned module, this pump is offered functional and ready to install, with the understanding that buyers should inspect seals, check valves, and pressure sensors as part of standard incoming maintenance. It provides a practical, lower cost way to keep an Agilent 1100 series HPLC system in reliable daily operation.
