Red PTFE/white Silicone septa Φ10*1mm temperature resistant -60℃-200℃

These 11 mm snap cap autosampler vials, caps, and septa are designed for reliable use in gas chromatography (GC) and liquid chromatography (LC) applications. The system is compatible with standard crimp-top caps, offering flexibility and convenience for laboratories performing routine chromatographic analysis.
The autosampler vials are manufactured from premium borosilicate glass, available in clear Type I Class A or amber Type I Class B glass. Each vial includes a write-on identification patch, allowing easy labeling and improved sample traceability during laboratory workflows.
The snap caps are produced from high-quality polypropylene, manufactured to precise tolerances to ensure consistent sealing performance. Caps are assembled in a controlled manufacturing environment to maintain reliability and product quality. A range of cap colors is available, including black, red, green, yellow, and blue, enabling quick visual identification of samples or analytical batches.
The septa are manufactured using high-performance materials designed to ensure reliable sealing and injection performance. Pre-slit septa options are available to facilitate smooth needle penetration during sample injection.
Each septum features a 0.035″ white silicone layer combined with a 0.005″ red PTFE barrier, providing excellent chemical resistance while protecting samples from contamination.
This vial, cap, and septum combination is designed for multiple injections and longer analytical cycles, making it suitable for both GC and LC autosampler systems. The use of high-quality silicone compounds ensures effective resealing after needle penetration and significantly reduces the risk of septum coring, helping maintain consistent analytical performance.
