Cost effective platinum counter and calomel Electrode

 

A pt counter electrode is basically used for some electrochemical techniques in standard electrochemical cells. These are used in many areas in the market because first it is oxidation, acids and solvents resistant and second it is available at a low rate. These counter electrodes or auxiliary electrodes offers input potential to a working electrode. They complete the circuit and permit the current to flow.

Another electrode type that is famously known is a calomel electrode. These are used as a reference electrode in corrosion studies and this is because they are available at a low cost. These can either be used as a cathode or an anode and is dependent on the nature of other electrodes in the cell. These electrodes are generally reference electrodes and the base of these electrodes is the reactions between elemental mercury and mercury chloride (calomel). The industries that use these electrodes are the manufacturing units of PH meters and voltmeters. These are robust in nature and hence are used in many two-electrode systems that have a non-reactive chloride salt as a supporting electrolyte.

A calomel electrode is made up of an outer glass tube that is fixed at the bottom through a frit. This allows electrical contact with an outside solution of the electrode. An inner tube is fitted in an outside tube. Inner tube bottom has glass wool that allows electrical contact between the contents of two tubes. The innermost tube has mercury paste with mercurous chloride dispersed in potassium chloride solution.

So, if you are from a business that makes use of these electrodes then you might desire them from a reliable online seller. You can contact Dek Research at their website for relative information.
