Open-top vial: Open-top vials feature an inert polypropylene screw cap. The cap has a hole in the center and a silicone or polytetrafluoroethylene layer, called the septum, underneath. The septum forms an airtight seal. With the open-top cap, an autosampler needle can easily pierce the septum and access the sample.

SureStop vials are designed as part of the Advance Vial Closure System (AVCS) and remove any subjectivity around achieving the optimal seal compression when closing a vial. Below are 2mL, 12x32mm vials in clear and amber glass with 9mm screw thread vials for use with AVCS caps to provide the ultimate in sample security. The 9mm AVCS closures

Screw and snap caps are usually made of plastic, mostly polypropylene (PP) or polyethylene (PE), whereas seals for crimp-top vials are made from aluminum. For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial.

Crimp top vials are the gold standard when concerned with evaporation, but crimp top GC vials are also common among laboratories requiring chain of custody, due to the tamper-proof caps. Most standard autosamplers accept 2mL (12 x 32mm) vials, which are the most common size of vials available.

Aug 05, 2020 · Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. Compared to other lids, crimp cap seal is the best. The crimp cap vial requires crimping tools to carry out the sealing process. The raw material of Crimp Caps are Metal or aluminum.

a true bond at the molecular level of the septa and plastic cap, eliminating excess evaporation and providing a proper seal with the vial. Septa are completely secure and will not fall into the vial during injection. These caps are made with PTFE/Silicone septa for excellent chemical resistance

11mm Patented Snap Top Caps™ may be snapped on and off by hand which eliminates the need for metal crimping and decapping tools, thus reducing potential hazards due to sharp aluminum metal edges. Large opening top provides a greater target area for needle penetration. Linerless Snap Seal™ Caps for Chromatography Vials are available with or without starburst.
