1260 Infinity Isocratic Pump 

The optimized design of the Agilent 1260 Infinity Isocratic Pump ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This delivery principle allows variable stroke volume optimized to selected flow rate. The broadened pressure range with maximum pressure of 600 bar allows the use of small particle size columns, longer columns, or alternative solvents of higher viscosity. It is the ideal pump for GPC/SEC applications  where run-to-run and day-to-day precision of retention times is important.
