Closures, SureSTART™, Level 2 Screw Caps, 13mm, High-throughput Applications

Use Thermo Scientific SureSTART 13mm Screw Caps with screw vials that have a 13mm opening, including our SureSTART 4mL Glass Screw Top Headspace Vials (Level 2). Select Level 2 products for high-throughput applications, when robustness and reproducibility are key. Choose from polypropylene and polyurethane caps with all-purpose silicone/PTFE septa or PE foam/PTFE septa designed to reduce autosampler needle issues. A pre-slit septa option is available for those who want septa that prevent vial-overfilling issues and re-seal well enough to avoid sample evaporation.

Our performance Level 2 caps are manufactured and tested to ensure low bleeding, robustness, and reproducibility of results for your routine GC-MS and LC-MS analyses.
