Featuring a dual-piston, servo-controlled hydraulic system with variable stroke technology and active damping, the G7104A delivers smooth, consistent flow with minimal pressure pulsation. Supporting flow rates from 0.001 to 5 mL\/min and operating pressures up to 1300 bar, the pump provides the flexibility and performance required for both conventional HPLC and high-pressure UHPLC separations.\u003cbr\u003e\u003cbr\u003eThe G7104A utilizes low-pressure quaternary gradient formation with an integrated four-solvent selection valve, enabling precise mixing and delivery of up to four solvents. Its low delay volume and accurate composition control support reproducible gradient separations across a wide range of analytical methods. Additional features include automatic compressibility compensation, integrated four-channel degassing, and an automatic purge valve for convenient system preparation and maintenance.\u003cbr\u003e\u003cbr\u003eDesigned for dependable operation and simplified maintenance, the G7104A incorporates advanced diagnostic capabilities, leak detection, and automatic shutdown signaling to help protect the instrument and maintain reliable performance. Early Maintenance Feedback (EMF) continuously monitors seal wear and pumped solvent volume, providing customizable maintenance alerts and electronic records of instrument activity. These integrated monitoring and maintenance features help minimize downtime and ensure consistent solvent delivery across demanding analytical workflows.\u003cbr\u003e\u003cbr\u003eAll of our
