Knauer Azura P2.1L Preparative HPLC Pump

AZURA preparative HPLC pump P 2.1L covers wide flow rate range and pressure capabilities. It has been designed for purification of mg and gram samples. The Mobile Control allows intuitive control in stand-alone operation.

The integrated automatic recognition of the pump head with RFID technology allows fast adaptions of the pump for various applications.

Preparative pump offers wide range of flow rates (0.1-1000 ml/min)
Choice of different LC software platforms
Improved electronic drive compensation
Integrated compressibility compensation
Integrated leak management
Constant pressure operation mode
