Cost-effective, isocratic HPLC pump with solvent selection valve and degasser

AZURA P 6.1L Isocratic Pump with 10 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 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 lowvolume 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.
