Conductivity monitor with flow cell for up to 100 ml/min and optional pH measurement

Conductivity monitor with optional pH measurement

The AZURA CM 2.1S is a reliable conductivity monitor which is utilized in FPLC to follow salt gradients. Optionally pH values can be measured. Wetted parts are completely biocompatible. The contactless measurements of conductivity reduces the risk of carryover to a minimum. The flow cell covers a flow rate up to 100 ml/min and is delivered with the CM 2.1S.
Please order the pH measuring kit in addition to the conductivity monitor.
