Agilent 1100 G1312A Binary Pump

Agilent 1100 G1312A Binary Pump


This Agilent 1100 Bin Pump has been fully tested, inspected and verified to be in great working condition.  60 Day Warranty at asking price!

We do have a 1200 series cover for the bin pump if you would like. Just let us know. We can include it.

The Agilent/HP 1100 Series G1312A Binary 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. 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.

  • Flow Precision: <0.3 % RSD (typically <0.15 % RSD)
  • Flow Range: Setpoints from 0.001 to 5.0 ml/min,  in 0.001 ml/min increments
  • Operating range: 0 – 40 MPa (0 – 400 bar, 0 – 5880 psi)
  • Pulsation: <2 % amplitude (typically <1 %) at 1 ml/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)
  • Compressibility compensation: User selectable, based on mobile phase compressibility
  • Delay volume: 180 – 480 µl (600-900 µl with mixer) dependent on back pressure
  • Recommended pH range: 1.0 – 12.5. Solvents with pH <2.3 should not contain acids which attack steel
  • GLP Features: Electronic records of maintenance and errors.
    Early maintenance feedback (EMF) for
    continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
