These versatile electrode holders are suitable for holding Carbon rod electrodes as well as metal strip electrodes. They are designed to fit over 100 mL and 250 mL glass beakers, being held in place by small plastic lugs to prevent them slipping off. Resistant to corrosion, they accept 6 - 8 mm diameter cylindrical (e.g. carbon) electrodes and 19mm wide, 0.8 mm (minimum) thick metal strip electrodes. The brass connectors also resist corrosion and are compatible with the usual 4 mm stackable type lab leads. To tighten the carbon electrodes without crushing them, the setscrew is equipped with stop. • 4 mm sockets • Dimensions (L x W x H): 100 x 40 x 15 mm • Complete with 2 carbon electrodes
These 'S' shaped electrodes are convenient and easy to use simply hang them over the rim of the beaker containing the electrolyte and connect crocodile clips with 4 mm leads to them! Made from insulated brass, with a short length of carbon rod attached at the lower end and bare contact at the top for attaching crocodile clip. Supplied as a pair of electrodes.
