Article No.: APG90FA

Compact HPLC pump with 50 ml/min pump head, stainless steel, without pressure sensor

The AZURA pump P 2.1S (APG90FA) is developed for the eluent delivery with flow rates up to 50 ml/min and a maximum delivery pressure of 150 bar. This compact pump can easily be integrated into every HPLC system. It can be used as a small HPLC pump, an injection module or dosing pump.


This device variant is the standard version with a pump head made of stainless steel.


The recommended range for continuous operation ist from 3 to 25 ml/min with a flow rate increment of 0.001 ml/min.
