CUSTOM ITEM: Caps, Screw Top, with ultra-clean Silicone Rubber / PTFE Septa, fitted in "knurled", polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK
Additional Info:
Provide enhanced cleanliness and reliable sealing for sensitive analytical workflows with screw top caps designed for high‑purity applications.
9502S-14C-B caps are manufactured with a knurled polypropylene design for improved grip and consistent handling during manual use. The ultra‑clean silicone rubber / PTFE septa is engineered to reduce potential contaminants and extractables, making it well suited for trace‑level analysis and demanding LC‑MS or HPLC workflows.
The bright white silicone indicates a higher level of cleanliness compared to standard septa materials, while the PTFE layer provides excellent chemical resistance and inertness. Together, these materials deliver dependable sealing and resealability during repeated injections, helping maintain sample integrity and analytical accuracy.
