BPPG
working electrode is chemically stable, is a typical working
electrode. Disk working electrode is most commonly used electrochemistry
measurements, example, Cyclic Voltammetry.
Disk electrode is easy to polish electrode surface for cleaning,
and easy to calculate the surface area.
Electrode size is as shown in the figure. The BPPG diameter
is 3.0 mm. The electrode body material is a Kel-F , which is
a fluorochemical product also known as PCTFE (polychlorotrifluoroethylene).
The outside diameter is 1/4"(inch); 6.35 mm. The CTFE seems
excellent than PEEK in heated sulfuric acid solution from the
user information. Listed below is the result of the immersion
solution each 7 days.
