SureSTART™ 20 mm GC Vial Stoppers (Level 2)

Choose SureSTART 20 mm Stoppers (Level 2) with 20 mm Crimp Vials or SureSTART 20 mm Crimp Headspace Vials (Level 2), available in various pack sizes of low permeability, 3 mm thick Bromobutyl Rubber Stoppers designed to provide a cost efficient alternative to septa. Level 2 stoppers undergo an additional conditioning process to reduce extractables.

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

Level 2 SureSTART 20 mm Stoppers are manufactured from low permeability bromobutyl rubber, making them suitable for low temperature gas analysis and low volatility gas storage.

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.
