The 1290 Infinity Quaternary Pump is the only pump combining the ultimate performance of a binary low-pressure mixing UHPLC pump with the flexibility of a quaternary pump. The 1290 Infinity LC power range allows you to run any HPLC and UHPLC method. The Agilent InletWeaver guarantees highest mixing efficiency before the mobile phase enters the pump head. Active damping combines innovative pump engineering with tuning algorithms embedded in the firmware for reduced ripples and associated UV noise. Additional mixing capacity is achieved with the optional Agilent V380 Jet Weaver. A multipurpose valve adds useful functionalities, e.g. mixer in/out switch, filter back flush or automatic purge. BlendAssist software simplifies your workflow with accurate buffer/additive blending.
