The Agilent/Hewlett Packard 1100 Series Binary Pump, Model G1312A, 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.

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.
