Agilent 1290 Infinity I HPLC G4220A Binary Pump

The Agilent 1290 Infinity I HPLC G4220A Binary Pump is expertly crafted to deliver exceptional performance and reliability for high-pressure liquid chromatography workflows. Featuring a two-channel, dual-piston in-series design with a proprietary servo-controlled variable stroke, it offers a settable flow range of 0.001–5.0 mL/min in precise 0.001 mL/min increments. With flow precision of ≤0.07% RSD and flow accuracy of ±1%, this pump provides unmatched accuracy for demanding analytical applications. It supports pressures up to 120 MPa (1200 bar) at 2 mL/min or 80 MPa (800 bar) at 5 mL/min, enabling high-throughput methods and efficient gradient formation. The high-pressure binary mixing system, coupled with the Jet Weaver for optimal mixing, ensures minimal delay volumes (<45 uL) while maintaining stability and efficiency.

Equipped with advanced features, including a two-channel integrated degassing unit with a 1.5 mL internal volume per channel, the pump ensures stable flow and enhanced detector sensitivity. Additional functionality, such as the solvent selection valve, automatic purge function, seal wash for pump longevity, and fast defill capabilities, optimizes usability and operational reliability. With updated dimensions of 9.3 × 13.5 × 17 inches and a weight of 48 pounds, the pump’s compact and robust design suits diverse laboratory setups. Researchers seeking precision, versatility, and dependability will find this pump an excellent addition to their laboratory.

All of our equipment is fully tested to perform at factory specifications before being shipped.
