Agilent 1200 HPLC G1312B SL Binary Pump with Dual-Piston In-Series Design
Product Description
- Settable Flow Range: 0.001 to 5 ml/min, adjustable in 0.001 ml/min increments
- Operating Flow Range: 0.1 to 5.0 ml/min
- Pressure Range: 0 to 400 bar (0 to 5880 psi) at up to 5 ml/min
- Design: Two-channel, dual-piston in-series pump assemblies for solvent metering and high-pressure delivery
- Pump Assembly Components: Includes pump drive, pump head, active inlet valve, and outlet valve per channel
- Mixing System: Low-volume mixing chamber connected to a capillary coil, followed by a damping unit and mixer for efficient solvent mixing
- Stroke Volume: Variable stroke volume enables pulse-free solvent delivery
- Active Inlet Valve: Electronically activated and synchronized with piston stroke; eliminates vapor formation with volatile solvents; maintenance-free
- Performance: Capable of generating pressures up to 400 bar, suitable for high-performance liquid chromatography (HPLC) applications
- Quality Assurance: All units are fully tested to conform to factory specifications prior to shipment
