Agilent 1100 HPLC G1311A Quaternary Pump
Product Description
Agilent 1100 G1311A Quaternary Pump
- Flow Range: 0.2 to 10.0 ml/min
- Flow Precision: <0.3% RSD
- Pressure Pulsation: <2% amplitude
- Operating Pressure: Up to 40 MPa (400 bar) at flow rates up to 5 ml/min
- Delay Volume: 800 – 1100 µl
Technical Features:
- Dual floating pistons in series enable virtually pulse-free solvent flow with precise servo control.
- Variable stroke volume allows efficient mixing and stable solvent delivery.
- Electronically activated inlet valve synchronized with piston stroke prevents vapor formation, maintenance-free.
- Flow settable from 0.001 to 10 ml/min with 0.001 ml/min increments ensures precise control.
- Low-pressure quaternary gradient mixing with proprietary high-speed proportioning valve.
- Compatible with solvents spanning pH 1.0 to 12.5.
- Compact dimensions: 5.5 x 13.5 x 17 inches for optimized bench space use.
This pump is engineered to deliver stable, precise solvent gradients critical for HPLC applications. It fully meets factory specifications and is ready for analytical laboratory deployment.
