1) Description
Aluminum Crimp Top Caps are used for vials in gas chromatography primarily due to their durability, ability to provide a tight seal, and resistance to various chemicals. Aluminum caps can effectively withstand high temperatures, which is crucial in gas chromatography processes where heat is often used. Additionally, these caps are less reactive with chemicals, reducing the risk of contaminating the sample. This ensures that the integrity of the sample is maintained, leading to more accurate and reliable results in chromatographic analysis.
2) Application
In the context of gas chromatography, aluminum-capped vials are typically used in environments where chemical stability and heat resistance are essential. This includes laboratories conducting chemical analyses, pharmaceutical testing, environmental sampling, and quality control processes. In these settings, samples often undergo high-temperature treatments or are exposed to reactive agents. Aluminum caps ensure a secure, airtight seal, preventing sample evaporation or contamination. Their chemical inertness also prevents reactions that could alter the sample. Overall, these caps are vital in maintaining sample integrity in various analytical and testing environments.
3) Features
▶ Caps are ready to use with any headspace crimp top vials.
▶ Pre-assembled caps and septa are convenient and minimize contamination from handling.
▶ It is autoclavable, easy sterilization.
▶ Very low background peaks, very low permeability.
▶ Both Aluminum,Magnetic,Bi-Metallic caps are available.
