11mm Silver Aluminum Crimp Closure with PTFE/Red Silicone Septum

This 11mm silver aluminum crimp closure features a high-quality PTFE/red silicone septum, engineered for reliable sealing in chromatography vials and autosampler applications. The PTFE-faced silicone septum provides excellent chemical resistance and low bleed characteristics, making it ideal for GC and HPLC analysis where sample integrity and reproducibility are critical. Designed for use with standard 11mm crimp-top vials, this closure ensures secure, leak-free sealing for volatile and sensitive samples.
