The AZURA pH 2.1S is a reliable pH monitor which is usually utilized in FPLC to follow buffer composition and elution conditions.
Please combine an external flow cell according to the systems tubing and flow rate. There are two flow cells availbe for flowrates between 0 - 100 ml/min or 100 ml/min - 1000 ml/min. The flow cell needs to be ordered separately.
