Red PTFE/white Silicone septa Φ11*1mm temperature resistant -60℃-200℃

These 11 mm snap caps, septa, and vials are designed for reliable use in gas chromatography (GC) and liquid chromatography (LC) applications. They are compatible with standard crimp-top cap systems, offering flexibility for laboratories that require secure and efficient sample handling.
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 clear sample labeling and traceability during analytical workflows.
The snap caps are made from high-quality polypropylene, produced under precise manufacturing tolerances to ensure consistent sealing performance. Caps are assembled in a controlled production environment to maintain reliability and product quality. Available cap colors include black, red, green, yellow, and blue, enabling easy visual identification of samples or analytical batches.
The septa are manufactured from high-performance materials to ensure optimal sealing and injection performance. Options include pre-slit septa, allowing smooth needle penetration and minimizing damage during repeated injections.
Each septum features a 0.035″ white silicone layer with a 0.005″ red PTFE barrier, providing excellent chemical resistance and protecting samples from contamination.
These vials and septa are specifically designed for multiple injections and longer analytical cycles, making them suitable for both GC and LC autosampler systems. The use of high-grade silicone compounds improves septum re-sealing after needle penetration while reducing the risk of coring, ensuring consistent analytical results and extended septum life.
