Assembled Target™ 10-425 Caps and Septa

Thermo Scientific™ 13mm Screw Thread Caps feature a 13-425 thread finish and are available in an assortment of styles to match your HPLC, GC or IC application needs. Convenient pre-assembled caps and septa minimize contamination from handling. Choose from Thermo Scientific™, Thermo Scientific™ National™, and Thermo Scientific™ Chromacol™ brands.

Use Thermo Scientific™ SureSTART™ 11 mm Snap Caps with snap vials that have an 11 mm opening, including our SureSTART 2 mL Glass Snap Vials, 1.5 mL Total Recovery Glass Snap Vials, High Recovery Glass Snap Vials, and Glass Snap 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 soft polyethylene caps with double snap functionality that guarantees a tight seal. Our snap caps include all-purpose silicone/PTFE septa of various hardness values designed to reduce autosampler needle issues. Pre-slit septa options are available for those who want septa that prevent vial-overfilling issues and re-seal well enough to avoid sample evaporation.

Thermo Scientific™ Open-Top Screw Caps provide an inert, airtight seal and direct puncture-access to sample with a syringe needle.

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.
