Product Code : SCL-AM-12099
Electrode Carbon Rod With Brass Terminal (SKU SCL-AM-12099) is an inert graphite electrode, 100 mm long and 5 mm in diameter, that carries current into an electrolyte without reacting with it. It is used for electrolysis of water and salt solutions, Faraday’s-law work and simple cells in school and college chemistry and physics labs. Science Lab Supplies supplies these electrodes from Ambala, India to schools, colleges, training institutes, tender contractors and distributors, packed as a kit with clip leads.

Applications and Experiments for the Electrode Carbon Rod
Carbon rods serve as inert anodes and cathodes, so the products seen in a practical come from the electrolyte rather than from the electrode. They are common chemistry lab equipment in India for gas-evolution, deposition and cell experiments, connected to a low-voltage DC supply through the clip leads.
- NCERT Class 10 science: electrolysis of water, collecting hydrogen at the cathode and oxygen at the anode, run from an AC/DC Laboratory Power Supply.
- Class 12 electrochemistry and B.Sc.: Faraday’s laws, comparing deposits with different currents, alongside a Hoffman Voltameter With Electrodes.
- Electrolysis of salt solutions, and redox and voltaic cell demonstrations with carbon as the inert electrode.
Never let the two electrodes touch while the supply is switched on. Hydrogen evolved during electrolysis is flammable and many electrolytes are acidic, so work under supervision. Rinse rods in distilled water after use and store them dry in their tube, since graphite is brittle.
Standard Scope of Supply
Each kit contains two carbon electrode rods of 100 x 5 mm, two insulated alligator clip leads in red and black, a protective cardboard storage tube and an experiment manual with electrolysis diagrams. The DC power supply, beaker and electrolyte are not included and can be quoted separately.
Packing, MOQ and Lead Time
You can ask for one kit or a stock of kits to equip every electrolysis station. Each quotation names the packing, delivery time and price for that quantity, and you may also ask for the carbon electrode price in India together with power supplies or voltameters.
Science Lab Supplies is registered with an Importer-Exporter Code, so it can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Requests are welcome on the contact page or through the enquiry cart, while bids and tenders are handled via the lab tender page.
Frequently Asked Questions
Why is graphite used for electrolysis electrodes?
Graphite conducts electricity well and is chemically inert in most acids, bases and salts, so it passes current into the electrolyte without dissolving or reacting during typical school electrolysis experiments.
What size are the rods?
Each rod is 100 mm long and 5 mm in diameter. Two rods are supplied per kit with red and black insulated alligator clip leads for connection to a DC supply.
Can the rods take high temperatures?
The synthetic graphite is rated to 400 °C in ambient air. In normal classroom electrolysis the rods stay far below that, but avoid dropping or bending them because graphite is brittle.
Who supplies the Electrode Carbon Rod With Brass Terminal?
Science Lab Supplies supplies it from Ambala, India. You can order the electrode kit together with power supplies, voltameters and other chemistry or physics items on one combined quotation.
