Electrode Rod Carbon Voltameter
Product Code : LSK-CL-10057
Electrode Rod Carbon Voltameter (SKU LSK-CL-10057) is a 100 x 10 mm carbon rod held in a glass tube with a terminal, intended as an electrode for voltameter work. Carbon is inert in most electrolytes, so the rod suits experiments in which the gases or deposits formed at each electrode are collected and measured. It is used in electrolysis practicals in school and college chemistry and physics. Spare and replacement electrodes of this type are supplied by Science Lab Supplies from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The carbon voltameter electrode is described one fact per row in the table. Briefly, it is a carbon rod measuring 100 x 10 mm, mounted in a glass tube and fitted with a terminal for a connecting lead, for use in electrochemistry experiments such as gas-collecting voltameters.

Applications and Experiments for the Carbon Voltameter Electrode
In a voltameter, two inert electrodes pass current through an electrolyte and the gases or deposits formed are measured. This carbon rod in its glass tube provides one of those electrodes, letting students relate the charge passed to the amount of product and compare gas volumes at anode and cathode.
- Class 10 science: electrolysis of acidified water and the 2:1 hydrogen-to-oxygen ratio, for example in the Apparatus for Water Electrolysis (Hoffman Voltmeter).
- Class 12 chemistry: Faraday's laws of electrolysis.
- B.Sc. physics and chemistry: electrochemical equivalent from gas volume, with the voltameter held on a Hoffman Voltameter Stand.
- Electrolysis of brine to show chlorine at a carbon anode, in a fume cupboard.
Glass is fragile: fit the electrode gently and check the tube for cracks. Acid electrolytes are corrosive and chlorine is toxic, so run these experiments under supervision.
Standard Scope of Supply
Each unit is a single carbon rod, 100 x 10 mm, fitted in its glass tube with a terminal. The voltameter body, power supply and electrolyte are not included; order two electrodes if your voltameter needs a matching pair, and add the other items to the same quotation.
Packing, MOQ and Lead Time
Single replacement electrodes or pairs for several voltameters can be quoted. Every quotation sets out packing, delivery time and price for the quantity you request, and voltameters, power supplies or other school chemistry lab equipment in India can be listed on it.
Science Lab Supplies has an Importer-Exporter Code and can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. When replacing worn electrodes, give the number of voltameters on the contact page or place the pairs in the enquiry cart; spares bought under a tender are handled through the lab tender page.
Frequently Asked Questions
Why use carbon for a voltameter electrode?
Carbon does not dissolve in most electrolytes used in teaching, so the electrode itself is not consumed and the gases or deposits measured come from the electrolyte rather than from the rod.
How does this differ from the plain carbon electrode rod?
Both use a 100 x 10 mm carbon rod with a terminal, but this version is mounted in a glass tube for voltameter use, while the plain Electrode Rod has only a terminal.
Who supplies the Electrode Rod Carbon Voltameter?
This electrode is a supplied item from Science Lab Supplies, Ambala, India, available as a spare or bundled on one quotation with voltameters, stands and other electrolysis apparatus.
Will it fit my existing voltameter?
Send the make or dimensions of your voltameter through the contact page, and fit will be confirmed before the quotation for the replacement electrodes is issued.
