Product Overview
This Puratronic™ cobalt foil delivers exceptional purity at 99.995% (metals basis), making it an ideal choice for demanding laboratory applications where trace impurities can compromise results. The 0.1mm (0.004in) thickness provides the perfect balance between structural integrity and flexibility, allowing for easy handling while maintaining dimensional stability. Engineered for consistency, this foil undergoes rigorous quality control to ensure uniform thickness and surface finish across each sheet. The Puratronic™ grade designation guarantees ultra-low impurity levels, with strict limits on metallic and non-metallic contaminants that could interfere with sensitive processes. Available in three practical sizes (100x100mm, 50x50mm, and 25x25mm), this cobalt foil adapts to various experimental setups without requiring additional cutting or modification. Its smooth, defect-free surface minimizes the risk of contamination during handling or storage. The foil’s high-density crystalline structure ensures excellent thermal and electrical conductivity, while its corrosion resistance extends its usable lifespan in diverse environmental conditions. Each piece is individually packaged to prevent oxidation and physical damage during transit, arriving in pristine condition ready for immediate use.
FAQs
1. What is the actual thickness tolerance for this cobalt foil?
The 0.1mm thickness has a typical tolerance of ±0.005mm, ensuring precision for critical applications where dimensional accuracy matters.
2. How does Puratronic™ grade differ from standard cobalt foil?
Puratronic™ grade represents the highest purity level available, with total metallic impurities limited to 50ppm maximum, compared to standard grades that may contain 100-500ppm impurities.
3. Can this foil be cut into smaller pieces without affecting its properties?
Yes, the foil can be carefully cut using precision shears or a laser cutter, though we recommend using the pre-cut sizes to maintain edge integrity and purity.
4. What storage conditions are recommended to maintain its purity?
Store in the original packaging at room temperature in a dry, inert atmosphere (nitrogen or argon) to prevent surface oxidation and contamination.
5. Is this foil compatible with vacuum chamber applications?
The high purity and low outgassing properties make it suitable for vacuum environments, though we recommend degassing at 150°C for 2 hours before use in ultra-high vacuum systems.
