SureSTART™ HPLC and GC Certified 2 mL Short Thread Screw Clear Glass SureStop™ Vial and 9 mm AVCS™ Screw Cap Kits with White Silicone/Red PTFE Septa, Level 3 - FAQs

What are SureStop vials?

In addition to the features on standard 2 mL vials, SureStop vials also have a patented definite stop point (alignment ring) in the design of the vial finish. This prevents the vial from being an optimal seal, which eliminates under- and over-sealing by the cap/closure and user-to-user variance.

SureStop vials are designed for use with Advanced Vial Closure System (AVCS) screw caps. They improve transfer reliability and give a more secure liquid seal than standard screw vials. SureStop vials are available as a 2 mL as either clear or amber options and are highly recommended for use with GC and LC applications.
