AGILENT G1311A 1100 Series Quaternary Pump HPLC for Sale

TheHP Agilent 1100 Series G1311A Quat Pumpis a component in the 1100 HPLC series. It ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This design with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke eliminates vapor formation with volatile solvents and is maintenance free. With high-speed proportioning valve and pre-configured vacuum degasser, for convenient low-pressure mixing of up to four solvents and highest flexibility in solvent choices.

The Agilent 1100 Series is one of the most rugged and durable liquid chromatograph systems on the market today. The G1311A is an optimized design ensuring virtually pulse-free and stable solvent flow with dual floating pistons. Instrument comes equipped with four solvent inlets with built-in gradient control. The gradient formation is performed by a low pressure gradient valve.
