Quaternary analytical HPLC pump
Article Nr.: APH34EA
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 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 quaternary pump contains one high pressure pump (700 bar) and an integrated LPG mixing block with a 4 × 2-channel inlet solvent selection valve and the new developed AZURA mixer, a low-volume mixing device.
