Use Thermo Scientific™ SureSTART™ Performance Level 3 Inserts with 2 mL vials when analyzing <2 mL samples to maximize the injection volume. These glass inserts have a small total volume capacity of <400 μL, with a minimum residual volume of 2 μL. When placed and sealed inside a 2 mL vial, microsamples can be used in conventional autosampler trays. Choose from polyspring conical, pulled point conical, or flat bottom insert formats. Conical inserts are most effective with residual volumes of 2-4 μL. These inserts are Performance Level 3, which means they are designed to protect your most valuable samples and deliver consistent, reproducible results for your most demanding analyses. They are Specification Certified to ensure physical dimensions and meet all requirements of US, EU, JPN Pharmacopeia.

Note: Purchase is for Glass Inserts Only


  • Use 9 mm screw top vials, 11 mm snap top vials, or 11 mm crimp top vials with these inserts
  • Seal these vials with 9 mm screw caps or 11 mm crimp/snap caps and the corresponding septa depending upon which vial type you use

Performance Level 3 Inserts – for High Performance Applications

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.
