This new platinum counter electrode kit features a 6.6 mm OD PTFE body and terminates with a coil of 0.5 mm OD platinum (Pt) wire featuring an approximate surface area of 4.7 cm². The Pt coil electrode is seated inside a fritted glass tube by means of a 7 mm OD 14/20 PTFE adapter. This fritted isolation tube has a 12 mm OD to 14/20 adapter such that the electrode and fritted tube can pass through a 14/20 port and seal within the ground glass joint. Both adapters enable adjusting the immersion depth of the electrode and isolation tube. The fritted glass tube isolates the counter electrode from the main test solution. This counter electrode is ideally designed for use with our Standard volume electrochemical cells, but is not limited to use in these cells. Customers who have no desire for the fritted isolation tube may consider using this product by itself, as fritted glass tube is not required for use and can be removed if desired. The platinum counter electrode can fit within a 14/20 port directly using its own adapter (included).
