Binary analytical HPLC pump

Article Nr.: APH35EA

The AZURA pump P 6.1L uses technology to overcome the challenges of pumping LC solvents at high pressure and high flow rates. This pump is designed to fulfill the needs for high pressure and low pressure mixing tasks.

The pump can deliver flow in the range of 0.001 – 10 mL/min at pressures up to 700 bar. The AZURA Binary Pump contains two identical high pressure pumps (700 bar),  2 × 2-channel inlet solvent selection valve and the new developed AZURA mixer, a low-volume mixing device.
