CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE, ultra-clean Septa, fitted in polypropylene, Blue Caps with a Gold, Magnetic Cover. For use with 9-425mm thread, 12x32mm autosampler vials. AQ Brand. BULK PRICING.

Additional Info:

Magnetic screw caps provide a convenient and reliable alternative to traditional crimp caps by eliminating the need for crimping and de‑crimping tools. Improperly crimped caps can lead to evaporation, leaks, and inconsistent analytical results. These magnetic screw caps help ensure consistent sealing performance with simple, repeatable application.

The 95040‑40‑T‑D AQ™ Caps are pre‑assembled with a gold magnetic cover over a blue 9‑425 polypropylene screw cap and a 1.0 mm thick, non‑slit silicone/PTFE septa. The ultra‑clean septa formulation is designed to reduce extractables and background interference, making these caps suitable for sensitive analytical methods.

These caps are specifically engineered for autosamplers that utilize magnetic closures, such as Thermo TriPlus™ systems, while remaining compatible with all standard 9 mm screw‑thread autosampler vials across BASIK™, MICROSOLV™, AQ™, and RSA™ product lines.

The silicone/PTFE septa provides reliable resealing for multiple injections while maintaining chemical resistance. The magnetic top allows automated handling by compatible instruments and ensures consistent cap placement in high‑throughput workflows.
