CUSTOM ITEM: Caps, Snap Top, with Silicone Rubber / PTFE Pre-Slit (X Shape) Septa, fitted in smooth, polyethylene, Yellow Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. BULK PRICING.
Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining reliable autosampler performance. The X‑shape pre‑slit septa increases the needle strike area, allowing easier alignment and reducing penetration resistance during injection.
The 9502C‑30CY‑X Snap Caps are a widely used configuration built on a proven design with over 25 years of trusted performance in laboratory environments. The silicone rubber / PTFE septa provide strong chemical resistance while supporting consistent sample handling across HPLC and LC‑MS workflows.
Pre‑slit septa are commonly recommended for Waters® Alliance instruments, where smooth needle entry is critical. The X‑slit design improves targeting and ease of penetration but provides slightly reduced resealing compared to single‑slit septa. The yellow polyethylene cap supports clear identification and efficient workflow organization.
