• May be used with or without stirring the medium
• Very stable output
• Very low rate of oxygen consumption
• Compatible with all Strathkelvin accessories
• 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. With these membranes, there is 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, (P/N SI 035) is used. Rapid stirring of the medium is then necessary. The electrodes are not temperature compensated and require to be used at controlled temperatures (within + or -0.05°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.

The SI020 Electrode Service Kit

The Electrode Service Kit contains six pre-membraned polypropylene jackets, abrasive cleaning membranes and a bottle of electrolyte solution.
