High-pressure gradient semi-preparative HPLC pump

AZURA P 6.1L High-Pressure Pump with 50 ml pump head, stainless steel, without Degasser

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 0.001–50 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 new developed AZURA® mixer, a low-volume mixing device. The AZURA® quaternary pump contains one high-pressure pump and an integrated LPG mixing block with a 4-channel inlet solvent selection valve and the new developed AZURA® mixer, a low-volume mixing device. The integrated degasser and AZURA® inline filter are completing the analytical AZURA® HPLC pump and turn this pump into a working horse in the lab. This pump is also available with wetted materials made from ceramic, PEEK and titanium for biocompatible applications.
