CUSTOM ITEM: Caps, Screw Top, with White Silicone Rubber / Natural TEF Septa, fitted in smooth sided, Robo Style, soft polypropylene, Blue Caps. For use with 9-425 thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.

Additional Info:

Provide a cost‑effective and chemically inert sealing solution with Robo style screw caps designed for routine chromatography workflows.

9502S-10-TEF caps feature a smooth‑sided, Robo style polypropylene design that is compatible with automated capping and decapping systems, while also providing easy manual handling. The white silicone rubber / natural TEF septa offers a reliable combination of flexibility and inertness, suitable for a wide range of HPLC and LC‑MS applications.

TEF septa provide chemical inertness comparable to PTFE for standard chromatography use, making these caps an economical alternative without compromising performance. The silicone backing supports resealing during repeated injections, while maintaining a secure seal for sample integrity. This configuration is commonly used as a lower‑cost option for routine laboratory workflows and as an alternative to Thermo™ and National DP™ caps.
