The Thermo Scientific™ 11 mm Snap Cap with Slit Polyethylene Septum is a high-quality chromatography closure designed for secure sealing of 11 mm snap-top autosampler vials used in HPLC, GC, LC-MS, IC, and other analytical applications. Manufactured from chemically resistant blue polyethylene (PE), the cap provides a reliable, easy-to-use sealing solution for routine laboratory sample preparation and analysis.
Designed with an integral slit polyethylene septum, the cap allows smooth autosampler needle penetration while maintaining an effective seal during repeated injections. The snap-on design eliminates the need for crimping or decapping tools, enabling quick application and easy removal for improved laboratory productivity. Thermo Scientific 11 mm snap caps are fully compatible with standard 11 mm Snap-It™ and SureSTART™ autosampler vials used in chromatography laboratories.
