CUSTOM ITEM: Caps, Screw Top, with Silicone Rubber / PTFE, low durometer Septa, fitted in "knurled", polypropylene, Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
Provide reliable sealing and easy handling with screw top caps designed for consistent performance in routine autosampler workflows.
9502S-10C-BX caps feature a knurled polypropylene design that improves grip during manual capping and removal, supporting efficient laboratory operation. The silicone rubber / PTFE septa combines chemical resistance from the PTFE layer with the flexibility of silicone, offering dependable sealing and compatibility with a wide range of solvents used in HPLC and LC‑MS methods.
The low durometer silicone septa allows easier needle penetration, reducing stress on autosampler components while still maintaining effective resealing during repeated injections. This balance of flexibility and performance makes these caps well suited for routine analytical use where dependable sealing and ease of use are required.
