Macherey-Nagel provides encapsulated N20 Headspace vials, designed for safe, reproducible, and efficient sealing in gas chromatographic analysis. Manufactured from hydrolytic class I borosilicate glass, these vials offer optimal chemical and thermal resistance, ideal for advanced techniques such as GC Headspace and SPME.

The N20 encapsulation allows a more consistent sealing process than traditional crimp closures, significantly improving result reproducibility. With a thinner septum, needle penetration is easier and produces less coring—crucial in SPME applications where septum integrity affects sampling accuracy. The closure design offers a flat surface for the magnet, preventing vial detachment during handling—an issue often seen with over-crimped vials due to convex cap shapes.

Available in clear or amber glass for light-sensitive compounds, N20 encapsulated vials are compatible with most autosamplers and automated systems, offering a robust and reliable solution for laboratories demanding quality and precision in Headspace analysis.
