Features of 1290 Quaternary Pump
- Binary pump-like performance in terms of accuracy and precision for flow and composition. Read more * Infinite power range combining ultrahigh pressure up to 1200 bar and high analytical flow rates up to 5 mL/min for maximum chromatographic performance * Integrated high efficiency degasser with low internal volume is based on PTFE AF technology and offers fast change-over of solvents for purging and priming the pump * Highest solvent mixing efficiency before reaching the pump head due to the new InletWeaver, based on established multilayer mixing technology * Active damping with independently controllable high resolution pump drives and firmware-embedded tuning algorithms significantly reduce ripples and associated UV noise, switchable V380 Jet Weaver for extra mixing volume * A multipurpose valve enables automatic software-embedded functionalities like switching the optional mixer in and out, flushing back the inline filter or automatic purging * Convenient, precise and accurate buffer/additive blending using the new software feature BlendAssist, implemented in the pump driver.
