Agilent 1200 Series G1312A Binary Pump

This used Agilent 1200 Series G1312A Binary Pump delivers high-pressure two-solvent gradient mixing, making it well suited to methods that demand fast, precise gradient transitions. As part of the Agilent 1200 Series, it offers strong pressure capability and smooth flow delivery for demanding separations, and it has been maintained in working condition for continued laboratory use. The binary architecture mixes solvents at high pressure before the pump head, which supports better gradient accuracy for fast or steep methods compared to low-pressure mixing designs. This pump is commonly chosen by laboratories running UPLC-style fast gradient methods or those needing tight retention time reproducibility, such as pharmaceutical stability testing or metabolite analysis. It integrates directly with Agilent 1200 Series autosamplers, column ovens, and detectors, and operates under standard ChemStation or OpenLAB control, allowing it to be substituted into an existing method without extensive revalidation. As a used module, this binary pump provides a cost-effective way to add high-pressure gradient capability to an Agilent LC system or to replace a failing unit while keeping the rest of the stack intact. It is a solid option for labs seeking dependable performance from familiar, proven hardware.
