Conductivity monitor with flow cell for up to 10 ml/min and optional pH measurement
Conductivity monitor with optional pH measurement
The AZURA CM 2.1S is a reliable conductivity monitor which is usually utilized in FPLC to follow salt gradients. By adding a pH sensor also pH values can be measured. Wetted parts are completely biocompatible. The contactless measurements of conductivity reduces the risk of carryover to a minimum. Note that the flow cell for up to 10 ml/min generates a certain back pressure (approximately 1 bar at 1 ml/min) due to the small inner volume.
