Product Overview
This Puratronic™ 99.99% lead foil delivers exceptional purity for demanding laboratory applications where trace impurities can compromise results. With a uniform 0.5mm (0.02in) thickness, it provides reliable shielding against radiation while maintaining flexibility for easy handling and custom shaping. The foil’s high-density composition ensures consistent performance in X-ray fluorescence, gamma spectroscopy, and other analytical techniques requiring precise attenuation. Its malleability allows for tight sealing in experimental setups without cracking, while the Puratronic™ grade guarantees minimal metallic contaminants, making it ideal for sensitive research environments. The corrosion-resistant surface maintains integrity over prolonged exposure to humidity or mild chemicals, reducing the need for frequent replacements. Available in standard 50x50mm and 25x25mm sheets, this foil is pre-cut for convenience but can be further tailored to specific dimensions without compromising structural uniformity. The 99.99% metals-basis purity exceeds typical commercial grades, ensuring reproducibility in critical experiments where material consistency is non-negotiable.
FAQs
1. What is the difference between Puratronic™ and standard lead foil?
Puratronic™ lead foil undergoes additional refining to achieve 99.99% purity, eliminating trace impurities like copper, silver, or bismuth that may interfere with sensitive measurements. Standard foils typically range between 99.9% and 99.95% purity.
2. Can this foil be soldered or welded for custom applications?
Yes, but low-temperature soldering is recommended to avoid altering the foil’s metallurgical properties. Use lead-tin alloys with a melting point below 200°C and avoid prolonged heat exposure to prevent oxidation.
3. How does the 0.5mm thickness compare to other common lead foil gauges?
This 0.5mm thickness offers a balance between shielding effectiveness and flexibility. Thinner foils (0.1–0.25mm) are more pliable but provide less attenuation, while thicker sheets (1mm+) offer superior shielding but are rigid and harder to cut.
4. Is this foil compatible with vacuum environments?
The foil’s low outgassing properties make it suitable for moderate vacuum applications, but prolonged exposure to high-vacuum conditions may require pre-baking to remove adsorbed moisture.
5. What precautions should be taken when handling this foil?
Wear nitrile gloves to prevent skin contact with lead, and use stainless steel tools to avoid contamination. Store in a dry, sealed container away from acids or oxidizing agents to preserve surface integrity.
