Product Name – Aluminum foil, 0.25mm (0.01in) thick, annealed, Puratronic™, 99.9999% (metals basis) Quantity/Pack Size – 100x500mm, 50x50mm, 100x100mm Form – Foil Grade – Puratronic™ (99.9999%) Application – High-precision lab experiments, contamination-sensitive processes

Product Overview

This ultra-high-purity aluminum foil is engineered for demanding laboratory applications where minimal impurities are critical. With a 99.9999% (metals basis) purity level and Puratronic™ certification, it ensures consistent performance in sensitive environments. The 0.25mm (0.01in) thickness provides durability while maintaining flexibility for easy handling. Annealed for uniform softness, this foil eliminates internal stresses, making it ideal for precise cutting, folding, or shaping without cracking. Its low impurity profile minimizes interference in analytical procedures, while the smooth surface prevents particle shedding. Whether used as a barrier, substrate, or protective layer, this foil delivers reliability in contamination-controlled settings. The three available sizes (100x500mm, 50x50mm, 100x100mm) cater to diverse experimental needs, from large-scale setups to micro-applications. Each sheet undergoes rigorous quality checks to meet Puratronic™ standards, ensuring traceability and reproducibility in research protocols.

FAQs

1. What is the significance of the Puratronic™ grade in this aluminum foil?

The Puratronic™ grade indicates an ultra-high purity level of 99.9999% (metals basis), meaning it contains less than 1 ppm of metallic impurities. This makes it suitable for applications where even trace contamination could affect results, such as semiconductor research or high-sensitivity spectroscopy.

2. Can this foil be used in high-temperature applications?

While aluminum foil generally withstands temperatures up to 400°C, prolonged exposure to high heat may cause oxidation or structural changes. For short-term use, it remains stable, but for sustained high-temperature applications, consider thicker gauges or alternative materials like quartz.

3. How does annealing improve the foil’s performance?

Annealing relieves internal stresses in the metal, making the foil softer and more malleable. This process enhances its ability to conform to surfaces without tearing, reduces brittleness, and ensures uniform thickness—critical for applications requiring precise dimensional stability.

4. Is this foil compatible with acidic or alkaline solutions?

Aluminum reacts with strong acids (e.g., HCl, H2SO4) and bases (e.g., NaOH), leading to corrosion. For such environments, use PTFE-coated aluminum or inert materials like Teflon. However, it resists mild organic solvents and neutral aqueous solutions.

5. What storage conditions are recommended to maintain its purity?

Store the foil in its original packaging or a sealed, moisture-proof container at room temperature (15–30°C). Avoid exposure to humidity, direct sunlight, or reactive gases, as these can degrade surface purity or cause oxidation over time.
