1mm Silver disk electrode, 3mm OD

This silver electrode is suitable for a variety of voltammetric experiments. It comprises a 3 mm OD PEEK tube that contains a 1 mm diameter silver disk at one end. This end is polished to a mirror finish. The disk is electrically connected to a 1 mm gold plated pin at the other end of the PEEK tube.

Silver electrodes are often used for the trace determination of halide and thiocyanate anions by cathodic stripping analysis.

PEEK (polyetheretherketone) is inert to most aqueous solutions including dilute acids and bases, and is also resistant to most organic solvents. It is not quite as inert as Teflon, but it holds its shape much better and will not easily separate from the embedded disk material.
