The electrolysis carbon rod is a conductive laboratory electrode used for passing electric current through a suitable electrolyte. It is intended for supervised school, college, university and training-laboratory experiments involving electrolysis, electrical conductivity, electrode reactions and the decomposition of ionic compounds in aqueous or molten systems.
Product Description
The STEMAids Electrolysis Carbon Rod provides a solid conductive surface that can function as an anode or cathode in a compatible electrochemical cell. Carbon electrodes are useful in instructional experiments because they conduct current while avoiding the introduction of a readily dissolving metal electrode in many common demonstrations.
Carbon should not be described as chemically inert under every condition. Electrode wear, oxidation or reaction may occur depending on the electrolyte, voltage, current density and products formed. The rod dimensions, carbon grade, purity and connector design are not currently published. Buyers should confirm these details before procurement through the STEMAids institutional sales team.
Key Features
- Electrically conductive carbon: Supports current flow through compatible electrochemical cells.
- Dual electrode use: Can serve as an anode or cathode according to the experimental circuit.
- Metal-free electrode surface: Helps avoid adding a readily dissolving metal electrode to selected classroom experiments.
- Visible reaction site: Allows students to observe gas evolution, deposits or other electrode changes.
- Reusable format: May be reused when structurally intact and chemically suitable for the next experiment.
- Simple circuit integration: Can be connected to a suitable low-voltage direct-current source using compatible leads.
- Broad electrochemistry utility: Supports electrolysis, conductivity and electrode-polarity demonstrations.

How to Use the Electrolysis Carbon Rod
- Select a compatible electrolyte, vessel and low-voltage direct-current source.
- Inspect the carbon rod for cracks, loose particles or previous chemical contamination.
- Attach the rod securely to a suitable holder or electrical clip.
- Position two compatible electrodes in the electrolyte without allowing them to touch.
- Connect the electrodes to the correct power-supply terminals.
- Apply the specified voltage and observe changes at each electrode.
- Switch off the power before adjusting or removing either electrode.
- Rinse, dry and inspect the rod after the experiment.
Safety note: Wear eye protection and suitable gloves. Use only teacher-approved electrolytes and low-voltage laboratory power supplies. Some electrolysis reactions can produce flammable, toxic or corrosive substances; identify all expected products before energising the cell.
Care & Maintenance
- Rinse the rod promptly using a procedure compatible with the electrolyte.
- Dry it completely before storage or electrical reuse.
- Do not use a cracked, deeply eroded or contaminated electrode.
- Store rods separately to prevent breakage and cross-contamination.

Frequently Asked Questions
What is an electrolysis carbon rod used for?
It is used as a conductive electrode in electrolysis, conductivity and other instructional electrochemistry experiments.
Can the carbon rod be used as both an anode and a cathode?
Yes, depending on how it is connected. Its chemical behaviour will differ with polarity, electrolyte and operating conditions.
Is carbon completely inert during electrolysis?
No. Carbon is comparatively unreactive in many demonstrations, but it can oxidise, erode or react under certain electrochemical conditions.
What are the rod dimensions?
The diameter and length are not published. Confirm both values for compatibility with the intended holder and vessel.
Are two carbon rods supplied?
The supplied quantity is not verified. Many electrolysis cells require two electrodes, so the bill of materials should be checked before ordering.
Can it be connected directly to mains electricity?
No. Use only a suitable isolated, low-voltage laboratory DC supply with current appropriate for the experiment.
