Product Description
When your research demands uncompromising purity, this Puratronic copper rod delivers. With a 99.999% metals basis, it’s engineered for experiments where even trace impurities can skew results. The 3.18mm diameter makes it versatile for electrical conductivity tests, calibration standards, or custom lab setups.
Unlike standard copper rods, Puratronic-grade material undergoes rigorous refinement to eliminate contaminants. This ensures consistent performance in sensitive applications like semiconductor research or high-precision instrumentation. The random lengths provide flexibility for cutting to your exact requirements.
Whether you’re a student verifying Ohm’s Law or a researcher developing advanced materials, this copper rod offers the reliability your work deserves. Need bulk quantities for large-scale projects? Eqipped provides competitive pricing on lab-grade metals—contact us for quotes.
Why High-Purity Copper Matters in Labs
Impurities in copper can alter electrical resistivity, thermal conductivity, and chemical reactivity. For example:
- In physics labs, even 0.001% impurities can affect resistivity measurements.
- Chemistry experiments may see unexpected reactions if oxygen or sulfur traces are present.
- Engineering prototypes require consistent material properties for accurate testing.
Puratronic copper eliminates these variables, giving you confidence in your data. The 99.999% purity meets ASTM and ISO standards for analytical-grade metals.
Common Applications
This copper rod is trusted in:
- Electrical resistivity standards
- Thermal conductivity experiments
- Corrosion studies
- Semiconductor research
- Custom electrode fabrication
Its uniform composition also makes it ideal for calibration samples in spectroscopy or mass spectrometry labs.
Handling and Storage
To maintain purity:
- Store in a dry, inert atmosphere to prevent oxidation.
- Use gloves when handling to avoid contamination from skin oils.
- Clean with acetone or isopropyl alcohol before critical experiments.
For long-term storage, consider vacuum-sealed containers or desiccators.
Safety Note
While copper is generally low-risk, always follow lab safety protocols. Avoid inhalation of dust during cutting or machining. Dispose of waste according to local regulations.
FAQs
What’s the difference between Puratronic and regular copper rods?
Puratronic copper undergoes additional refinement to achieve 99.999% purity, removing trace elements like iron, nickel, and oxygen that can affect experimental results. Standard copper may contain up to 0.1% impurities.
Can I use this for electrical wiring projects?
While it’s technically possible, Puratronic copper is overqualified for general wiring. Its high cost is justified for lab use where purity is critical. For wiring, consider standard electrical-grade copper.
How do I cut the rod to specific lengths?
Use a fine-toothed hacksaw or a low-speed diamond cutter to minimize burrs. Secure the rod in a vise and wear safety goggles. For precision cuts, a lathe or CNC machine is ideal.
Is this copper rod suitable for vacuum applications?
Yes, its high purity makes it excellent for vacuum systems. However, degassing may be required if used in ultra-high vacuum (UHV) environments.
Do you offer certificates of analysis (CoA) for this product?
Yes, eqipped provides CoAs with every shipment, detailing the exact composition and purity levels. Contact our support team if you need additional documentation.
