Choose Thermo Scientific™ SureSTART™ 2 ml GOLD-grade clear glass screw and crimp top vials, performance level 3, when analysing analytes such as polar compounds that strongly adsorb on the glass surface or are sensitive to sample pH changes.

Level 3 vials are designed to protect your most valuable samples and deliver consistent, reproducible results for your most demanding analyses. This offering includes Thermo Scientific™ SureStop™ vials, which, when used with 9 mm AVCS™ screw caps, ensure an optimal seal every time. The SureStop vial-AVCS cap system is specially designed to prevent screw thread vial failures such as cap tilt, cap deformities, dislodged septa, or septum push through, thus preventing injection failures and sample evaporation.
