LabSen pH Electrodes

The LabSen series brings together pH sensor technologies and key materials from Switzerland, with more than 30 models so that each application has a suitable electrode. The LabSen 211 and 213 are refillable electrodes for general water solutions, compatible with TRIS buffers; the 213's S-type hemispherical glass membrane stabilises in 15 to 30 seconds and is ten times stronger than a conventional membrane, its blue gel electrolyte prevents air bubbles, and its patented pH/temperature structure speeds the temperature response by 40%.

Other models are shaped for the sample: the LabSen 221 for titration and low-ionic-strength solutions, the 241 micro electrodes for micro-volume samples, NMR tubes and test tubes, the 251 spear for solid samples, the 371 and 373 flat electrodes for surfaces, and the 331, 333 and 335, whose open junction and polymer electrolyte eliminate junction clogs in wastewater, emulsions and suspensions. Models such as the 211, 213 and 331 use a long-life reference system that improves stability and extends service life, and the electrodes connect by BNC, with RCA temperature connectors on pH/temperature models.
