Caps, Snap Top, with Silicone Rubber / PTFE Pre-Slit Septa, fitted in smooth, polyethylene, Green Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. 100/PK.
Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining reliable autosampler performance. The pre‑slit septa design reduces needle resistance during injection, supporting smoother penetration and improved consistency.
The 9502C‑30CG Snap Caps are one of the most popular snap cap configurations on the market, with over 25 years of proven laboratory performance. The silicone rubber / PTFE septa provide excellent chemical resistance while maintaining resealing capability for multiple injections in HPLC and LC‑MS workflows.
Pre‑slit septa are commonly recommended for Waters® Alliance instruments, where consistent needle entry and reduced resistance are critical. The green polyethylene cap supports color‑coded organization and easy identification in high‑throughput laboratory environments.
