DESCRIPTION
These 20 mm crimp vial caps come equipped with grey butyl rubber stoppers, offering excellent chemical resistance and an airtight seal for headspace vials with a 20 mm neck diameter. The butyl rubber stopper provides superior elasticity and resealability, making it ideal for repeated needle punctures in headspace GC, HPLC, and other analytical applications. Compatible with standard 20 mm headspace vials, these caps ensure reliable sample integrity and minimal contamination. Supplied in a pack of 100, they are perfect for high-throughput laboratory environments.
