Microcathode Oxygen Electrode Model 1302

Microcathode Oxygen Electrode Model 1302

This is a Clark-type polarographic electrode with a 22 micron diameter platinum cathode and silver/silver chloride anode connected by a buffered potassium chloride electrolyte solution. In the normal configuration the cathode is covered with a relatively low permeability polypropylene membrane, in order for the electrode to be used in unstirred solutions or where minimal stirring is required. This membrane gives a relatively slow response time. For fast response, as required for rapidly respiring enzyme preparations, a thin FEP membrane (used with a special electrode jacket, (69-3011) is used. Rapid stirring of the medium is then necessary. The electrodes are not temperature compensated and require controlled temperature environments (within 0.1°C). They should always be used in the electrode holder of one of the Strathkelvin accessories, so that only the tip of the electrode is exposed to the medium.
