These disk electrodes are small and easy to use. All are manufactured in a solvent-resistant PCTFE plastic body (7.5 cm length x 6 mm OD) which is embedded with highly polished disks of various electrode materials (glassy carbon, gold, platinum, palladium, nickel, or silver). There is also an electrode body designed for use with carbon paste (also available from BASi) or new composite materials of your own design and an electrode body designed as a working electrode holder with an alligator clip. A brass rod (1/16”) mounted in the plastic body of the electrode is used to connect these electrodes to an appropriate instrument using either an alligator clip or a 0.060" gold-plated female connector (MF-2004). Each electrode comes with a silicon O-ring which fits snugly on the plastic body. By rolling the O-ring to different positions, you can change the depth of the electrode mounted in an electrochemical cell. Surfaces are polished to a mirror finish and easily maintained with the BASi® PK-4 polishing kit, which is sold separately.
