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. Level 2 SureSTART 20 mm Crimp Caps feature:• Pressure Release Cap Design – The cap has a perforated ring which will split if the septum is pushed upwards by high internal pressure. This releases the seal to allow pressure to release safely.• Molded Pharmafix Septa – These septa are composed of a hard central area of PTFE embedded within an outer and upper covering of a softer butyl elastomer.• High Temperature Septa – A specialized silicone formulation allows these septa to be heated to over 250°C without excessive septum softening or the release of volatile vapors. The SureSTART Performance Levels • Level 1: Everyday analysisChromatography 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 analysisWhen robustness and reproducibility are keySureSTART Level 2 products have very low metal contents, extractables, and leachables to ensure that they conform to the high standards you need to meet your regulatory requirements. These products support routine analyses and deliver high quality data with an uninterrupted workflow. • Level 3: High performanceWhen sensitivity is a mustSureSTART Level 3 products are packed in clean rooms to protect against environmental factors. They contain the lowest levels of metals, extractables, and leachables to ensure consistent, reproducible sensitivity and selectivity for the most challenging analytes. 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.
