Aluminum 20mm Crimp Seals

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 and 2 mL Polypropylene Screw Microvials for <2 mL samples (Level 1). Select Level 1 caps for chromatography approved, cost optimized products that are suitable for everyday analyses and compatible with all instrument types. Choose from polypropylene caps with silicone/PTFE or rubber/TEF 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.

Minimize contamination from handling with convenient, pre-assembled Thermo Scientific™ 11 mm Autosampler Vial Crimp Caps, compatible with most HPLC and GC autosamplers. Choose from Thermo Scientific™, National™ or Chromacol™ brands.

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.
