2） Product Overview
Aluminum construction withstands the high-temperature conditions common in gas chromatography workflows. It features outstanding chemical inertness and barely reacts with test substances, eliminating the risk of sample contamination. The stable seal fully preserves sample integrity and delivers precise, repeatable chromatographic data.
3） Key Features
- Universal fit for all standard crimp neck headspace vials
- Pre-assembled cap and septum design for easy operation and reduced manual contamination risks
- Autoclavable structure to support convenient high-temperature sterilization
- Ultra-low gas permeability and minimal background interference peaks during testing
- Three cap styles optional: pure aluminum, magnetic aluminum and bi-metal caps
4) Applications
Aluminum crimp caps are essential for scenarios requiring superior chemical stability and heat resistance. Widely adopted in chemical analysis labs, pharmaceutical testing, environmental monitoring and industrial quality control.
Samples in these fields frequently experience high-temperature heating or contact with reactive reagents. The caps form a fully airtight barrier to stop sample volatilization and external pollution, while their inert surface avoids unwanted chemical reactions that distort sample composition. They reliably protect sample stability across all analytical testing scenarios.
