Agilent 1100 Binary Pump (G1312A)



  • Agilent 1100 Binary Pump (G1312A)
    • CAN Cable
  • In-House Warranty Coverage


  • Installation & Familiarization
  • Extended Warranty

This Agilent 1100 Binary Pump comes expertly refurbished from GenTech Scientific.


  • Lowest volume capillary connections.
    • Two dual-piston, in-series pumps in one housing for a minimum of bench space and lowest internal and external volume. Only 180 – 480 µl internal volume (without mixer).
  • Low flow.
    • Starting at typically 50 µl/min for reproducible gradients at low flow with solvent degassing.
  • Reliable design.
    • With electronically controlled active inlet-valves for flow rates up to 5.0 ml/min, the Agilent 1100 Binary Pump is also ideally suited to standard-bore chromatography. Floating pistons with path-of-least-resistance principle ensures highest seal lifetime.


  • 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) continuously tracks binary pump usage and displays feedback messages if preset limits are exceeded.
