Lab Automation equipment uses different reagents for sample processing and instrument cleaning throughout the various processes. The bottles are interchangeable with unpredictable changing liquid compositions. Cross contamination between reagents must be minimized, which prevents the use of a measurement solution that is in direct contact with the reagents. Balluff's industry leading portfolio of capacitive sensors consistently and reliably detects liquid levels either through the container wall or through a sight glass. In addition, with Balluff's patented hybrid capacitive technology foaming and filming of conductive liquids are ignored.
