SureSTART™ 2 mL GOLD 등급 유리 스크류 및 크림프 탑 바이알, 레벨 3 고성능 애플리케이션

SureSTOP vials are designed for compatibility with nearly every LC or GC autosampler. They are part of the SureSTART family, which is tested for autosampler compatibility and specification certified for physical dimensions.

Under stress conditions (e.g., 1.3 mL methanol at 40 °C for 72 h), SureSTOP vials with AVCS closures lose significantly less solvent compared with generic screw-top or even crimp vials. The “definite stop” means the cap is tightened correctly (neither under nor over-tightened) so septum compression is predictable, and cap-tilt or septum displacement (which lead to evaporation paths) are minimized.

In workflows where solvent loss or sample concentration change is critical (as for very low volumes or volatile analytes), SureSTOP vials offer measurable improvement.

SureSTOP vials are well-suited for:
• GC, LC and MS workflows where volatile or semi-volatile solvents are used and evaporation or sample loss is a concern.
• High-sensitivity or trace-analysis workflows where variation in sealing can impact reproducibility.
• Labs where autosampler failures (due to cap/tilt/septum issues) are affecting throughput.

Key aspects of SureSTOP vials include:
• The “definite stop” design prevents over-tightening (which might deform the septum or the vial neck) and under-tightening (leading to leaks or evaporation).
• Achieve the best performance with caps that have Advanced Vial Closure System (AVCS) technology that levels and aligns the cap properly, reducing cap tilt and septum displacement.
• Demonstrated lower solvent loss (evaporation) in stressed tests compared with generic vial and closure combinations.

The SureSTOP vials are 2 mL screw-thread (9 mm) vials that incorporate a patented “definite stop point” in the vial finish (alignment ring) so when you use them with AVCS (Advanced Vial Closure System) 9 mm screw caps, you cannot under- or over-tighten the closure. This feature helps solve problems such as inconsistent sealing, variable septum compression, vial/septa push through, sample evaporation, or autosampler failures due to poorly sealed vials.
