The Agilent 1260 Infinity II Iso Pump  (G7110B) is designed for demanding QA/QC tasks as well as routine applications. It maintains virtually pulse-free and stable solvent flows. The dual floating, precise servo-controlled pistons in the delivery mechanism adjust the stroke volume according to the user's chosen flow rate.

The pump can deliver a broad range of pressures up to a maximum 600 bar, giving the user flexibility to use small particle size columns, longer columns or alternative higher viscosity solvents. The Agilent 1260 Infinity II Iso Pump (G7110B) is the ideal pump for GPC/SEC applications where run-to-run and day-to-day precision in retention times is crucial.
