Use Performance Level 3 Thermo Scientific™ SureSTART™ 2 mL GOLD-Grade Polypropylene Screw Top Microvials for <2 mL samples that are prone to non-specific binding. These low-bind polypropylene vials have been coated with a 200nm thick layer of 100% silicon dioxide providing superior chemical inertness and performance. The surface is free from anions and cations, minimizing adsorption and ensuring that even trace-level samples are recovered reliably.

They can be used with all HPLC/UHPLC instrument types. These clear plastic 2 mL screw top vials are Specification Certified to ensure autosampler compatible physical dimensions.

Choose from a variety of kits containing short thread screw vials and polypropylene caps with silicone/PTFE septa designed to reduce autosampler needle issues. Pre-slit and bonded septa options are available. Select kits with AVCS™ screw caps for effective seals, consistent data, and increased sample throughput.

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.
