The Agilent Technologies 1260 Infinity Preparative Pump (G1361A) is a high-performance HPLC pump designed for preparative liquid chromatography applications requiring high solvent flow rates and precise flow control. Its dual-piston, parallel design features cam-driven pistons with fixed stroke lengths and overlapping delivery cycles to ensure smooth and consistent mobile phase delivery.
The pump supports flow rates up to 100 mL/min and operating pressures up to 400 bar. It features user-adjustable compressibility compensation, an integrated automated seal wash system, and an electromagnetic purge valve. The G1361A can operate as a standalone isocratic pump or be combined with a second preparative pump to create a high-pressure binary gradient system.
