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. Two flow cells cover a flow rate up to either 10 ml/min or 100 ml/min and are optimized for low dead volume. Please order the conductivity flow cell and the pH measuring kit in addition to the CM 2.1S.
