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.
