Electrode Carbon Rod With Brass Terminal

Product Code : SCL-AM-12099

The Electrode Carbon Rod is a highly conductive graphite component used for facilitating electron transfer in electrochemical cells and electrolysis experiments. Engineered for chemistry student groups and research laboratories, this durable element provides an inert electrical pathway to safely evaluate chemical changes without contaminating the electrolyte solution.

Product Description

This premium graphite element offers an exceptional, cost-effective solution for chemistry classrooms, secondary schools, and academic research installations. Fabricated from high-purity, fine-grain synthetic graphite, each rod guarantees uniform electrical conductivity and high resistance to thermal shock. The high density of the carbon matrix ensures slow degradation rates, preventing carbon sloughing into solution during high-current operations.

For institutions adding to their essential collection of foundational chemistry lab equipment, these carbon rods deliver outstanding didactic value. They allow students to observe oxidation-reduction mechanics, gas evolution, and electroplating configurations firsthand. Choosing this grade of laboratory instruments guarantees reliable visual confirmation of ionic migration vectors without ambient contamination.

Key Features

• High Purity Synthetic Graphite: Manufactured from premium fine-grain carbon to prevent heavy metal contamination during sensitive electrochemical reactions.
• Excellent Electrical Conductivity: Provides low electrical resistance to ensure steady current transmission across variable voltage ranges.
• Chemically Inert Profile: Resists chemical attack from most standard acids, bases, and salts, making it perfect for diverse electrochemical cells.
• Standardized Geometry: Formed into a uniform cylinder size that slots smoothly into standard educational alligator clips and rubber stoppers.
• High Thermal Deflection: Withstands elevated localized temperatures generated during intensive, long-duration electrolysis runs.
• Smooth Extruded Texture: Finished with a clean exterior surface to minimize particulate shedding and ease post-experiment cleanup.

How to Use the Electrode Carbon Rod

1. Fit the Electrode Carbon Rod through a pre-drilled rubber stopper or secure it with a mechanical clamp over the cell beaker.
2. Attach an insulated alligator clip lead tightly to the exposed upper dry margin of the graphite cylinder.
3. Connect the opposite end of the lead wire to the designated terminal of a variable low-voltage DC power supply.
4. Submerge the lower half of the carbon rod into the electrolyte solution matrix, ensuring it does not touch opposing electrodes.
5. Activate the DC supply power slowly to begin gathering bubble evolution metrics or tracking electrodeposition changes.
6. Turn off the electrical current source immediately once the planned data acquisition cycle concludes.

Safety Handling Note: Never allow the positive and negative electrode elements to make direct structural contact while the electrical power supply is active to prevent hazardous short circuits or equipment damage.

Care & Maintenance

• Cleaning: Rinse the rod thoroughly with distilled water immediately after use to clear acidic or basic residues, then pat dry with a lint-free cloth.
• Storage: Keep the rods inside their protective cardboard storage tube in a dry cabinet to shield the brittle graphite structure from impact breakage.
• Handling: Avoid applying high bending forces or dropped shocks onto concrete surfaces to prevent fracturing the carbon rod element.

Frequently Asked Questions

Why is graphite used for electrolysis electrodes?

Graphite is highly conductive and chemically inert, meaning it allows electrical current to flow into the electrolyte without reacting with the solution or dissolving away during most experiments.

Can these carbon rods be used in high-temperature configurations?

Yes, our high-density synthetic graphite handles temperatures up to 400°C in open air without degradation, making it excellent for intensive classroom voltaic cells.

Are these electrodes compatible with universal alligator clips?

Yes, the uniform 5 mm diameter profile fits securely inside standard educational alligator clips and standard chemical laboratory clamp setups.

Do these rods shed carbon particles into the solution?

Our rods are extruded from high-purity, fine-grain synthetic graphite to dramatically minimize physical shedding and maintain excellent solution clarity.

Can you cut or shape these rods for custom experiment arrays?

While the rods arrive ready for classroom use, graphite can be machined or carefully cut with a fine-toothed hacksaw to meet specialized custom setup configurations.
