Agilent 1100 HPLC G1311A Quat Pump

The Agilent 1100 G1311A Quaternary Pump 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. The Agilent quaternary pump is equipped with a 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.

All of our equipment is fully tested to perform at factory specifications before being shipped.
