Low pressure gradient HPLC pump for Ultra High Pressure Applications


AZURA P 6.1L Low Pressure Pump with 5 ml pump head, stainless steel

The AZURA® Pump P 6.1L uses technology to overcome the challenges of pumping LC solvents at high pressure and defined flow rates. This pump is designed to fulfill the needs for either high pressure or low pressure gradient forming. The pump can deliver flow in the range of 0.001–50 ml/min at pressures up to 1000 bar (depending on model). The AZURA® binary pump contains two identical high pressure pumps, a 2×2-channel inlet solvent selection valve and the low-volume AZURA® mixer. The AZURA® quaternary pump contains one high pressure pump and an integrated LPG mixing block with a 4-channel inlet solvent selection valve and a low-dwell volume AZURA® mixer. The integrated degasser and AZURA® inline filter are completing this analytical AZURA® P 6.1L HPLC pump and turn it into a work horse in the lab. This pump is also available with wetted materials made from ceramic, PEEK and titanium for biocompatible applications.
