Product Description

The Chromatography headspace septa 2ml is a certified headspace vial closure designed for precise GC analysis, compatible with 2ml vials. It features a high-quality PTFE/silicone septum ensuring optimal sealing integrity across -40°C to 260°C, ideal for volatile compound retention. Certified for ISO compliance, these GC headspace vial caps 2ml provide leak-proof performance under pressures up to 15 psi, minimizing evaporation and sample contamination. Widely used in pharmaceuticals, environmental testing, and food/beverage industries, their key advantages include chemical inertness, reusability, and compatibility with autosamplers. The main limitation is manual crimping tool dependency for installation. The septa’s 8-12 mm crimp diameter and 1.3 mm thickness ensure consistent sealing, while boron-free glass vials (recommended) prevent interference in sensitive detectors.
