    Agilent 1100 Series - G1310A HPLC Isocratic Pump

    Agilent 1100 Series - G1310A HPLC Isocratic Pump

    Cambridge ID #: 14776

    The HP / Agilent 1100 HPLC series is the current model and arguably the best design in the industry because of the optimized design of the quaternary pump ensuring 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.

     

     Features:

    • Ease-of-use - handheld control module lets you enter operating parameters fast, store methods easily and display pressure profile, diagnostics and task-oriented information.
    • Durable - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime. Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs.
    • Wide flow range - up to 10 ml/min for broad HPLC work, including semi-preparative separations.
    • Better for GLP - built-in leak and pressure test with graphical presentation of pressure profiles, and early maintenance feedback.

     

    Specifications:

    • Hydraulic system: Dual piston in series pump with proprietary servo-controlled variable stroke drive, floating pistons and active inlet valve
    • Settable flow range: .001– 10 ml/min, in 0.001 ml/min increments
    • Flow range: 2 – 10.0 ml/min
    • Recommended pH range: – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel.
    • Operating voltage: 230V
