G1311A Quaternary Pump for Agilent/HP 1100 HPLC


Categories: ,

This Agilent 1100 Series G1311A Quaternary Pump is in excellent condition.  The Agilent 1100 Series is one of the most rugged and durable liquid chromatograph systems on the market today.  The G1311A is an optimized design ensuring virtually pulse-free and stable solvent flow with dual floating pistions.  An inlet valve electronically activated and synchronized to piston stroke eliminates vapor formation with volitale solvents and is maintenance free.  Instrument comes equipped with four solvent inlets with built-in gradient control.  The gradient formation is performed by a low pressure gradient valve.

System specifications include:

  • Setable Flow Range: 0.001 – 10ml/min – in 0.001ml/min increments
  • Flow Range: 0.2 – 10.0 ml/min
  • Recommended pH Range: 1.0 – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel
  • Gradient Formation: Low pressure quaternary mixing/gradient capability using proprietary high-speed proportioning valve. Delay volume 800-1100µl, depending on back pressure
