ET087-3 Nickel Disk Electrode - Pack of 3
This nickel electrode is suitable for a variety of voltammetric experiments. It comprises a 3 mm OD PEEK tube that contains a 1 mm diameter nickel 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.
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.
