Product Overview

This high-purity aluminum foil, with a 99.997% metal basis purity, is engineered for demanding laboratory applications where contamination control is critical. The 0.25mm (0.01in) thickness provides an optimal balance between durability and flexibility, making it suitable for delicate procedures without compromising structural integrity. The Puratronic™ grade ensures trace metal impurities are minimized, offering reliable performance in analytical, research, and industrial settings. Its uniform composition and consistent thickness eliminate variability in experimental results, while the foil’s inert properties prevent unwanted reactions with samples or reagents. Whether used for sample preparation, shielding, or as a protective barrier, this aluminum foil maintains its integrity under thermal and chemical stress. The foil is supplied in precise dimensions (100x500mm and 100x100mm) to minimize waste and adapt to various experimental setups. Its smooth surface finish further reduces the risk of particle shedding, ensuring clean and reproducible outcomes in sensitive applications.

FAQs

1. What is the maximum temperature this aluminum foil can withstand?

This Puratronic™ aluminum foil can withstand continuous exposure to temperatures up to 400°C without significant degradation, though short-term exposure to higher temperatures may be possible depending on the environment.

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

The foil exhibits good resistance to weak acids and bases but may corrode when exposed to strong acids like hydrochloric or sulfuric acid or highly alkaline solutions for prolonged periods.

3. Are there alternative thicknesses available for this grade of aluminum foil?

While this specific product is 0.25mm thick, other Puratronic™ aluminum foils may be available in different thicknesses, though stock availability varies.

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

Store the foil in its original packaging in a cool, dry environment away from direct sunlight and chemical vapors to prevent oxidation or contamination.

5. Does this foil contain any trace elements that could interfere with sensitive analyses?

The 99.997% purity ensures minimal trace elements, but residual impurities (typically <30 ppm total) may include iron, silicon, and copper, which are documented in the certificate of analysis.
