Agilent 1260 Infinity II HPLC G7112B Binary Pump
Product Description
- Flow Range: Settable from 0.001 to 5.0 mL/min in 0.001 mL/min increments
- Recommended Flow Range: 0.05 to 5.0 mL/min
- Flow Precision: ≤ 0.07% RSD or ≤ 0.02 min SD, whichever is greater
- Pressure Range: Up to 60 MPa (600 bar, 8700 psi)
- Pump Design: Two dual-piston in-series pumps with servo-controlled variable stroke drive
- Gradient Formation: High-pressure binary gradient capability for accurate solvent mixing
- Delay Volume: Adjustable between 600–900 µL, depending on back pressure
- Solvent Compatibility: Stainless steel-compatible solvents, recommended pH range of 1.0 to 12.5
- Integrated Degasser: Two-channel degasser with 0.45 mL volume per channel for flow stability
- Additional Features:
- Predefined compressibility compensation based on mobile phase properties
- Bypassable pulse damper and mixer optimized for low flowrate applications
- Pressure sensor for continuous monitoring
- Applications: Supports conventional, superficially porous particle, and STM column technologies; suitable for high-throughput and fast-gradient HPLC methods with UV or MS detection
- Fully factory-tested for performance and reliability before shipment
