platinum plate counter auxiliary electrode

For quantitative electro-chemical analysis in laboratories, Platinum Electrodes of various types are used. Generally, Electrodes are made of platinum 10% Iridium alloy for added mechanical strength which ensure long period of trouble free service. Electrode cylinders are usually made of wire gauze having wire diameter 0.15 mm * 360 mesh per cm2. This provides greater surface than area equal weight of plain or perforated platinum sheet and allows the electrolyte to circulate much more freely. Wherever agitation of electrolyte is required in order to save time of deposition, one of the rotating type of electrode is used.

For most electro-chemical analysis, wire gauze cathode is most satisfactory while a small size of similar anode is used if an anode deposit is required.

A simple helix of wire with stem is an adequate anode where there is no anodic deposit or when determining is not more than 0.2 percent lead as lead peroxide.

If desired, we can manufacture Platinum 10% Iridium electrodes to customers’own specifications to meet their special needs.
