8mm Autosampler Vial 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.

Provide unique, practical seals that are ideal for chemicals that deteriorate or evaporate in conventionally sealed containers with the Thermo Scientific™ Mininert Valves. Constructed of chemical-resistant PTFE coating, they provide an inert, leak-tight, high-pressure seal. The easy-to-use push button valve allows repeated and unlimited syringe-needle access to samples and eliminates the septum-boring that occurs with repeated puncture of traditional septa. Valves are available to fit Thermo Scientific™ Reacti-Vial™ Small Reaction Vials and Thermo Scientific™ Screw Cap Septum Vials.

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.
