Agilent 1260 Infinity II HPLC G7112B Binary Pump

The Agilent 1260 Infinity II HPLC G7112B Binary Pump is designed for high-performance liquid chromatography applications, delivering precise and reliable solvent delivery. With an operating pressure of up to 600 bar and a flow range of 0.001 to 5.0 mL/min, it supports conventional, superficially porous particle, and STM column technologies. The pump employs a two-channel, dual-piston in-series design for robust gradient formation via high-pressure mixing, ensuring accurate and reproducible gradients.

Equipped with a two-channel integrated degasser (0.45 mL per channel), it offers exceptional flow stability, particularly at low flow rates, enhancing detector sensitivity. Key features include user-configurable standard or low delay volumes, a bypassable pulse damper and mixer for low flowrate applications, and a pressure sensor for continuous monitoring. Ideal for high-throughput and fast-gradient methods, the pump delivers unmatched speed and resolution for routine applications with UV or MS detection, ensuring uncompromised data quality.

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