Product Overview

This Puratronic™ 99.9999% aluminum foil is engineered for demanding laboratory environments where ultra-high purity and consistency are critical. The 0.5mm (0.02in) thickness ensures durability while maintaining flexibility for precise handling in sensitive procedures. Annealed for enhanced malleability, this foil minimizes internal stresses, reducing the risk of contamination or structural failure during experiments. The 99.9999% metals basis purity guarantees negligible trace element interference, making it ideal for applications requiring extreme chemical accuracy, such as semiconductor research, thin-film deposition, or high-vacuum systems. The foil’s uniform surface finish and dimensional stability provide reliable performance across repeated use cycles. Compatible with most standard lab equipment, it integrates seamlessly into existing workflows without requiring specialized handling protocols. The material’s resistance to oxidation and corrosion further extends its usability in both inert and reactive environments. Whether used as a substrate, shielding material, or sample holder, this aluminum foil delivers reproducible results with minimal batch-to-batch variation, ensuring data integrity in critical research applications.

FAQs

1. What is the difference between annealed and non-annealed aluminum foil?

Annealed aluminum foil undergoes a heat treatment process to soften the material, improving flexibility and reducing internal stresses. This makes it easier to shape and less prone to cracking compared to non-annealed foil, which retains higher rigidity but may be more susceptible to stress-induced failures during handling or thermal cycling.

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

The foil can withstand moderate temperatures up to ~200°C without significant structural degradation. For applications exceeding this range, consider shorter exposure durations or additional thermal shielding, as prolonged high-temperature exposure may affect dimensional stability or surface properties.

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

While aluminum inherently reacts with strong acids and bases, this high-purity foil offers improved resistance due to its minimal impurity content. For short-term exposure, it may be used with dilute solutions, but prolonged contact with corrosive substances is not recommended without protective coatings or alternative materials.

4. How should this foil be stored to maintain its purity?

Store the foil in its original packaging or a sealed, moisture-resistant container at room temperature. Avoid exposure to humidity, direct sunlight, or reactive gases, as these can accelerate surface oxidation or contamination. For long-term storage, consider using desiccants to maintain a dry environment.

5. Are there lower-purity alternatives available for less critical applications?

For applications where 99.9999% purity is unnecessary, standard laboratory-grade aluminum foils (typically 99.5%–99.9% purity) are available. These offer cost savings while still providing adequate performance for general-purpose tasks like sample wrapping, basic shielding, or non-analytical experiments.
