Description
The Agilent 1260 Infinity II G7104C Flexible Pump is a quaternary solvent delivery module engineered for accurate low‑pressure gradient formation in analytical HPLC workflows. It enables controlled blending of up to four solvents while maintaining stable flow and pressure behavior across a wide operating range.
Designed as part of the 1260 Infinity II platform, this pump supports reproducible chromatographic performance in routine and advanced analytical applications. It is commonly used where flexible solvent selection, consistent gradients, and automated operation are required.
This refurbished Agilent 1260 Infinity II G7104C Flexible Pump has been fully tested and verified to be in proper working condition by Alliant Scientific.
