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 volatile solvents and is maintenance free.  Instrument comes equipped with four solvent inlets with built-in gradient control. 

Specifications:

• Configurable 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
