KNAUER High Precision AZURA P 6.1L HPLC Pump

The KNAUER AZURA P 6.1L is a high-precision analytical HPLC pump designed for accurate and reproducible solvent delivery in both HPLC and UHPLC applications.

The pump combines essential features of a modern pumping system, including low pulsation, high pressure capability, precise gradient formation, and flexible configuration. It is available in both HPG (high-pressure gradient) and LPG (low-pressure gradient) versions, with a flow range up to 50 mL/min.

The system uses a dual serial piston mechanism with active pulsation compensation, ensuring excellent flow stability under all conditions. A low-dead-volume microfluidic mixer enables efficient and precise solvent mixing.

Different pump heads are available:

• up to 10 mL/min at 862 bar
• up to 5 mL/min at 1000 bar

Optional configurations include biocompatible materials (PEEK, ceramic, titanium) and specialized setups for normal phase applications (e.g., hexane, heptane).
