Aluminum 20mm Crimp Seals

Prevent septa push through and over- and under-tightening. With Advanced Vial Closure System (AVCS) technology built into 9 mm Thermo Scientific™ 9 mm Autosampler Vial Screw Caps and Septa you will get an optimal, consistent seal every time. With just one turn, they offer easy-on, easy-off convenience, and are a cost effective alternative to caps with bonded septa. Choose from Thermo Scientific™, Thermo Scientific™ National™, and Thermo Scientific™ Chromacol™ brands.

Use Thermo Scientific™ SureSTART™ 9 mm Screw Caps with screw vials that have a 9 mm opening, including our SureSTART 2 mL Glass Screw Vials, 2 mL Gold-Grade Glass Screw Vials, Total Recovery Glass Screw Microvials for <2 mL samples, 1.7 mL High Recovery Glass Screw Vials, and Glass Screw Microvials for <2 mL samples (Level 3). Select Level 3 products for ultimate performance and sensitivity from your methods, while maintaining the highest levels of sample security and integrity. Choose from polypropylene caps with all-purpose silicone/PTFE septa designed to reduce autosampler needle issues. Pre-slit and bonded septa options are available. Our AVCS™ caps incorporate Advanced Vial Closure System technology to ensure optimal seal compression when closing a vial. Use AVCS screw caps with our SureStop™ vials for effective seals, consistent data, and increased sample throughput.

Use Thermo Scientific™ SureSTART™ 20 mm Crimp Caps with crimp vials that have a 20 mm opening, including our SureSTART 10 mL and 20 mL Glass Crimp Top Headspace Vials (Level 2). Select Level 2 products for high-throughput applications, when robustness and reproducibility are key. Choose from aluminum and magnetic steel caps with silicone/PTFE or butyl/PTFE septa of various hardness values designed to reduce autosampler needle issues. Caps with Pressure Release technology will split to allow the safe release of high internal vial pressures. Use Thermo Scientific™ Manual or Electronic Crimpers and Decappers for easy application and removal of crimp caps.

Use Thermo Scientific™ SureSTART™ 18 mm Precision Screw Caps with screw vials that have an 18 mm opening, including our SureSTART 10 mL and 20 mL Screw Top Headspace Vials (Level 3). Select Level 3 products for ultimate performance and sensitivity from your methods, while maintaining the highest levels of sample security and integrity. Choose from magnetic steel caps with all-purpose silicone/PTFE septa designed to reduce autosampler needle issues. Select High Temperature septa to allow for heating to over 250°C without excessive septum softening or the release of volatile vapors.
