Description
The Hewlett Packard G1311A Quat Pump is a quaternary solvent pump designed for precise and stable solvent delivery in HPLC applications. With dual floating pistons ensuring pulse-free operation, this pump features electronically synchronized inlet valves that prevent vapor formation, effectively minimizing maintenance needs. It accommodates four solvent inlets with built-in gradient control, allowing for flexible solvent mixture and gradient formation. The flow range of 0.001–10 ml/min and pH range of 1.0–12.5 make it adaptable for various laboratory applications while ensuring compatibility with solvents. This preowned unit powers on with no errors, however, further tests such as flow and pressure were not conducted due to lack of chromatography software connection. Originally from a functioning lab environment, it displays cosmetic wear typical for used equipment.
Technician comment
Unit powers on with no front-panel errors. Functional testing (flow, pressure, leak check, gradient) was not performed because it was not connected to chromatography software during evaluation. Unit is preowned from a working lab environment. See photos for details.
