Agilent 1200 Series G1361A Prep Pump

This is a used Agilent 1200 Series G1361A Preparative Pump, built to deliver the higher flow rates required for preparative scale liquid chromatography and compound purification. Unlike analytical pumps designed for small bore columns, the prep pump is engineered to handle larger flow volumes reliably, supporting isolation and purification work where sample quantity, not just detection, is the goal. This pump is a common fixture in medicinal chemistry, natural products isolation, and process development labs that need to scale up purification of target compounds from milligram to gram quantities. It fits into the broader Agilent 1200 Series preparative HPLC platform alongside compatible fraction collectors, detectors, and autosamplers, allowing labs to maintain or rebuild a functioning prep-scale purification line. Its robust construction is suited to the demanding duty cycles typical of repeated purification runs. Offered in used, operational condition, this prep pump provides a budget conscious path to restoring or expanding preparative HPLC capacity. Labs adding this unit to an existing system should verify flow accuracy and check valve function as part of standard incoming qualification before resuming production purification work.
