    The new AZURA® P 8.1L UHPLC pump offers a maximum delivery pressure of 124 MPa/1240 bar and a flow rate range up to 5 ml/min for ultra-fast and high-resolution applications.

    The adaptive pulsation compensation of the pump is independent of flow rate, backpressure, and eluent type through real-time eluent compressibility monitoring and variable piston stroke. Together with the ultra-precise piston movement thanks to KNAUER’s proprietary advanced piston drive technology, this results in outstanding flow reproducibility at any working conditions. The pump also features a 2-channel internal degassing unit, a 2x2 channel solvent selection valve, and a low dwell-volume eluent mixer.

    Developed with innovative technology and decades of continuous improvements the AZURA® P 8.1L UHPLC pump enters a new level of performance and durability. With a high level of in-house component production KNAUER achieves an industry-leading level of manufacturing precision. This results in unmatched piston seal life and system uptime.
