Agilent 1260 Infinity I HPLC G1311B Quaternary Pump with Integrated Vacuum Degasser
Product Description
Agilent 1260 Infinity I HPLC G1311B Quaternary Pump
- Flow Accuracy: ±1% or 10 µL/min
- Settable Flow Range: 0.001 to 10 mL/min, increments of 0.001 mL/min
- Flow Range: 0.2 to 10.0 mL/min
Key Features:
- Robust two-channel, dual-plunger in-series design for precise solvent delivery
- Generates solvent gradients through low-pressure mixing of four individual solvent channels
- Variable stroke volume enables virtually pulse-free, stable solvent flow
- Pump assembly capable of producing pressures up to 600 bar for efficient high-pressure solvent delivery
- Integrated 4-channel vacuum degasser embedded in the quaternary pump for effective solvent degassing
- Solvent compositions controlled on the low-pressure side via a high-speed proportioning valve
This pump system incorporates all essential functions for gradient solvent delivery in HPLC applications, ensuring reliable and stable performance under high-pressure conditions.
