Description

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 2 mL Polypropylene Screw Microvials for <2 mL samples (Level 1). Select Level 1 caps for chromatography approved, cost optimized products that are suitable for everyday analyses and compatible with all instrument types. Choose from polypropylene caps with silicone/PTFE or rubber/TEF septa 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 1 caps are cost-efficient and quality tested to deliver the performance, sample security, and reproducibility you need for everyday analyses.

SureStop Vials & Advanced Vial Closure System (AVCS) Caps:
This patented screw top vial/cap combination features a push-through resistant sealing ring design, controlled septum compression, and SureStop closure positioning flange to ensure an effective seal that eliminates under- and over-sealing, reduces solvent evaporation, and creates less autosampler interruptions. SureStop vials and AVCS caps have universal instrument compatibility for all LC and GC autosamplers. They also contain low leachable levels, making them an ideal alternative to bonded caps for those seeking cleaner spectra.

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.
