LC chromatography pump AZURA P 4.1S

With its small footprint, the compact dual piston pump AZURA P4.1S can be used for a wide range of laboratory tasks. It features an integrated pressure sensor, which ensures pressure-independent flow rate accuracy. Moreover, for system protection, the pump drive is switched off when reaching a pre-defined pressure limit. Pump heads with maximum flow rates of 10 and 50 ml/min are available. A pressure rating of up to 400 bar and chemical resistance to a wide range of eluents make it the perfect choice for LC and dosing applications. Its exchangeable pump head allows adaptation of the pump for delivery of aggressive media and bioinert applications. The pump head can be heated or cooled with optional accessories. DPG22EA is the article number for a module integrated in the assistant. To order the device separately use APG22EA.
