The Agilent 1290 Infinity Binary Pump (G4220A) comes refurbished and delivers the industry’s widest analytical power range for ultimate chromatographic performance and flexibility. Lowest delay volumes allow you to run ultra fast gradients for narrow-bore applications. Active damping combines innovative pump engineering with tuning algorithms embedded in the firmware for significantly reduced ripples and associated UV noise. Background noise is reduced further by the Agilent Jet Weaver mixer, which is based on multi-layer technology.
Specifications:
- Hydraulic system: Two dual pistons in series pumps with proprietary servo-controlled variable stroke design, power transmission by ball screws, smooth motion control of pistons for active. damping.
- Settable flow range: Setpoints 0.001—5 ml/min, in 0.001 ml/min increments.
- Flow precision: ≤0.07 % RSD or 0.005 min SD, whatever is greater (0.2—5.0 ml/min). Based on retention time at constant room temperature.
