Short description

The high-grade platinum electrode tip with glass shaft has been specially designed for the determination of organic additives in galvanic baths using CVS (Cyclic Voltammetric Stripping).

It is of course also useful for any other application carried out on platinum electrodes, especially if aggressive media are involved. Platinum as the electrode material and the glass shaft are the only materials that come into contact with the measuring solution. This means that the electrode tip has excellent chemical resistance and a long life – even in electrolytes such as concentrated mineral acids or organic solvents. The platinum rod is embedded into the glass by fusion. There is no gap between the two materials and no need for any filling or adhesive material. The perfectly polished surface of the platinum tip results in exceptionally low background currents – profit from this decisive advantage!

Each electrode tip carries an indelible serial number and thus can always be identified. Each electrode tip is accompanied by an individual test certificate, which facilitates GLP-compliant docu-mentation.
