SureSTART™ 9 mm Screw Caps, Level 2 High-throughput Applications

Use Thermo Scientific™ SureSTART™ 9 mm Screw Caps with screw vials that have a 9 mm opening, including our SureSTART 2 mL Glass Screw Vials and 1.7 mL Glass High Recovery Screw Microvials for <2 mL samples (Level 2). Select Level 2 products for high-throughput applications, when robustness and reproducibility are key. Choose from polypropylene caps with all-purpose silicone/PTFE septa of various hardness values designed to reduce autosampler needle issues. Pre-slit and bonded septa options are available. Our AVCS™ caps incorporate Advanced Vial Closure System technology to ensure optimal seal compression when closing a vial. Use AVCS screw caps with our SureStop™ vials for effective seals, consistent data, and increased sample throughput.

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.

The SureSTART Performance Levels

SureSTART vials, caps, inserts, septa, and kits are available in three performance levels. Now you can choose the products that best suit your analytical, performance, or budget needs.

Level 1: Everyday analysis

Chromatography approved

SureSTART Level 1 products are cost optimized, suitable for all instrument types, and quality tested to deliver the performance, sample security, and reproducibility you need for everyday analyses. They are an ideal solution for verifying compound presence and quantification using detection techniques such as UV, RI, and FID.

Level 2: High-throughput analysis

When robustness and reproducibility are key

SureSTART Level 2 vials have very low metal contents and leachables to ensure that they conform to the high standards you need to meet your regulatory requirements. The septa are conditioned to provide a very low level of chromatographic extractables. These products support routine analyses and deliver high quality data with an uninterrupted workflow.

Level 3: High performance

When sensitivity is a must

SureSTART Level 3 products are packed in a clean environment according to our own hygiene concept and regulations to protect against contaminating factors. The vials contain the lowest levels of extractable metals and leachables to ensure consistent, reproducible sensitivity and selectivity for the most challenging analytes. The septa are conditioned to provide the lowest level of chromatographic extractables. Choose these products for ultimate method performance and high levels of and sample security and integrity.

All SureSTART vials, closures, and septa are certified to meet physical parameter specifications as part of our manufacturing process.
