DESCRIPTION
These 20 mm aluminum crimp caps come with chemically inert PTFE /silicone septa, designed for secure, leak-proof sealing of headspace vials with a 20 mm neck diameter. The PTFE /silicone septa provide excellent chemical resistance and minimize contamination, ensuring sample integrity during headspace GC, HPLC, and other analytical workflows. Compatible with most standard 20 mm headspace vials, these caps ensure reliable performance and easy autosampler compatibility. Supplied in a pack of 100, ideal for high-throughput laboratories requiring consistent vial sealing.
