Product Overview

This high-purity 99.99% aluminum foil is engineered for laboratory applications requiring superior thermal conductivity, chemical inertness, and contamination control. With a precise thickness of 0.1mm (0.004in), it offers an optimal balance between flexibility and durability, making it ideal for wrapping sensitive samples, creating moisture barriers, or functioning as a heat shield in experimental setups. The foil’s ultra-pure composition minimizes trace element interference, ensuring reliable results in analytical procedures. Its smooth, non-porous surface prevents absorption or leaching, while its malleability allows for easy cutting and shaping to fit custom lab requirements. The foil is resistant to corrosion and oxidation, maintaining integrity even under prolonged exposure to varying temperatures or humid conditions. Its lightweight yet robust structure makes it a versatile choice for both routine and specialized lab tasks where consistency and purity are paramount.

FAQs

1. What is the maximum temperature this aluminum foil can withstand without degrading?

The foil remains stable up to approximately 600°C in dry conditions, though prolonged exposure to high heat may cause slight oxidation. For short-term use, it can handle temperatures closer to its melting point of 660°C without structural failure.

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

While aluminum is generally resistant to weak acids and bases, strong acids (like hydrochloric or sulfuric) or highly alkaline solutions (pH >10) may corrode the foil over time. For such applications, consider a PTFE-coated variant or alternative barrier materials.

3. Can this foil be autoclaved for sterilization?

Yes, the foil can be autoclaved at standard 121°C/15 psi conditions for 15–20 minutes without compromising its integrity. Ensure the foil is dry before autoclaving to prevent steam-induced pitting or adhesion to other surfaces.

4. How does the 99.99% purity compare to standard household aluminum foil?

Household foil typically contains 98–99% aluminum with additives like iron or silicon for strength, which can introduce contaminants. This 99.99% pure foil eliminates trace metals, making it suitable for sensitive analytical work where elemental interference must be minimized.

5. What’s the best way to cut this foil cleanly without fraying the edges?

Use a sharp utility knife or precision scissors with a fresh blade, and cut against a firm, flat surface like a cutting mat. For intricate shapes, score the foil lightly with a razor before bending to snap along the line.
