Description

Dependable performance for low-volume sample analysis. Use SureSTART Polyspring Inserts (Level 1) for everyday LC and GC analyses.

Choose Thermo Scientific Polyspring Plastic Inserts with 2 mL Screw, Crimp, or Snap HPLC and GC Vials to maximize injection volume when analyzing 2 mL samples. The integral Polyspring at the bottom of the insert centers the insert in the vial, ensures a good seal with the vials' cap, and provides a cushion against needle contact. These plastic inserts have a small total volume capacity of 325 μL and a minimum residual volume of 2 μL. When placed and sealed inside a 2 mL vial, microsamples can be used in conventional autosampler trays. Performance Level 1 products are cost-optimized and designed for everyday chromatography analyses. They are Specification Certified to ensure physical dimensions.

Frequently Asked Questions (FAQs)

What are SureSTART micro inserts?

The micro inserts have a small total volume capacity of <400 µL and can be classified as either Polyspring, conical, or flat-bottom within the SureSTART Collection. Micro inserts are placed and sealed inside a vial so they can be used in conventional autosampler racks. The smaller 6 mm diameter of the insert gives better sample recovery than a routine flat based vial with conical inserts being most effective with residual volumes of 1-2 µL. Many are held in place by a Polyspring, which cushions and centers the insert.
