Product Overview

This ultra-pure aluminum foil is engineered to meet the most demanding laboratory requirements, offering exceptional 99.9995% purity (metals basis) under the Puratronic™ grade. The foil maintains a precise thickness of 0.038 ± 0.007mm (0.0015 ± 0.0003in), ensuring consistent performance in applications where uniformity and minimal impurities are critical. Its high-purity composition eliminates trace contaminants that could interfere with sensitive experiments or analytical processes. The foil’s smooth surface and dimensional stability make it suitable for thin-film deposition, electron microscopy sample preparation, and other high-precision tasks. Unlike standard aluminum foils, this Puratronic™ variant undergoes rigorous purification to achieve its ultra-low impurity levels, providing researchers with a reliable material for reproducible results. The foil is supplied in convenient sheet sizes (50x1000mm and 50x200mm) for easy handling and minimal waste during cutting or shaping. Its inert properties also make it resistant to oxidation under controlled conditions, further enhancing its utility in controlled environments.

FAQs

1. What is the significance of the 99.9995% purity in this aluminum foil?

The 99.9995% purity (metals basis) ensures that trace impurities are reduced to parts-per-million levels, which is critical for applications where even minor contaminants could skew results, such as in semiconductor research or high-resolution imaging.

2. Can this foil be used for vacuum deposition processes?

Yes, the ultra-thin 0.038mm thickness and high purity make it suitable for vacuum deposition techniques, including physical vapor deposition (PVD), where consistent material properties are essential.

3. How does Puratronic™ grade differ from standard aluminum foil?

Puratronic™ grade undergoes advanced refining to remove metallic and non-metallic impurities, resulting in a foil with significantly lower defect densities and higher chemical consistency compared to commercial-grade alternatives.

4. What precautions should be taken when handling this foil?

To prevent contamination, use clean gloves and tools when handling. Store in a dry, inert atmosphere to avoid oxidation or particulate accumulation on the surface.

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

While aluminum is reactive to strong acids and bases, the high purity of this foil reduces the risk of unintended reactions from impurities. However, compatibility should be tested for specific chemical exposures.
