The Gator’ consists of a brass rod (0.75 cm) mounted in the plastic body of the electrode. The upper end of the rod is used to connect these electrodes to an appropriate instrument using either an alligator clip or a 0.060" gold-plated female connector (QVMF2004).
The lower end of the rod has an alligator clip soldered to the device and covered with a heat shrink. 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 substrate mounted in an electrochemical cell (QVMR1195 and QVMR3818).
