The Agilent Technologies 1260 Infinity Preparative Pump (G1361A) is designed for preparative HPLC applications, providing precisely controlled mobile phase flow rates up to 100 mL/min. Its dual-piston pumping system features two parallel pistons with fixed stroke lengths and a cam-driven mechanism. Overlapping piston delivery cycles and motor speed regulation ensure smooth and stable mobile phase delivery.
The G1361A operates within a pressure range of 20–400 bar and offers user-selectable compressibility compensation for different mobile phases. The pump incorporates an automated seal wash system and an electromagnetic purge valve. It can be used independently for isocratic separations or combined with a second preparative pump to form a high-pressure binary gradient system.
