Product Overview
This Puratronic™ lead slug delivers ultra-high purity at 99.999% (metals basis), making it ideal for applications requiring minimal trace impurities. The 6.35mm (0.25in) diameter and length provide a standardized form factor for consistent experimental reproducibility. Engineered with exceptional density (11.34 g/cm³) and low melting point (327.5°C), this lead slug offers superior thermal and electrical conductivity while maintaining excellent corrosion resistance in ambient conditions. The material’s soft, malleable nature allows for easy machining or shaping without compromising structural integrity. Each batch undergoes rigorous spectroscopic analysis to ensure compliance with Puratronic™ grade specifications, guaranteeing traceability and reliability for sensitive laboratory procedures. The inert surface properties minimize reactivity with common lab reagents, while the uniform composition eliminates variability in experimental results. Available in 25g and 100g pack sizes to accommodate both small-scale testing and bulk applications.
FAQs
1. What is the typical surface finish of these Puratronic™ lead slugs?
The slugs feature a smooth, as-cast surface with minimal oxidation, though minor tool marks may be present from the manufacturing process. For critical applications, additional polishing may be required.
2. Can these lead slugs be used in vacuum environments?
While lead has low outgassing properties, prolonged exposure to high-vacuum conditions may require pre-treatment to remove surface contaminants. Degassing at 150°C for 24 hours is recommended for ultra-high vacuum applications.
3. What is the difference between Puratronic™ and standard commercial-grade lead?
Puratronic™ lead undergoes additional refining steps to achieve 99.999% purity, eliminating trace elements like copper, silver, and bismuth that are typically present in commercial grades (99.9% purity).
4. Are these slugs compatible with acid digestion procedures?
The high-purity lead resists corrosion from dilute mineral acids but will dissolve in concentrated nitric acid. For digestion protocols, use PTFE-lined containers and limit exposure time to prevent contamination.
5. How should these slugs be stored to prevent oxidation?
Store in a desiccated environment below 25°C, ideally in sealed polyethylene bags with silica gel packets. Avoid prolonged exposure to humid air or chlorine-containing atmospheres to prevent surface tarnishing.
