ET052-3 Platinum Dsk Electrode - Pack of 3
This platinum electrode is suitable for a variety of voltammetric experiments. It comprises a 3 mm platinum disk in a 6 mm OD PEEK body. The tip is polished to a mirror finish. The disk is electrically connected to a 2 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.
