CUSTOM ITEM: Caps, Snap Top, with Silicone Rubber / PTFE Pre-Slit (Y Shape) Septa, fitted in smooth, polyethylene, Blue 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 Y‑shape pre‑slit septa increases the available needle strike area, allowing improved alignment and reduced penetration resistance.
The 9502C‑34CB Snap Caps use a silicone rubber / PTFE septa construction that provides chemical resistance and dependable performance across HPLC and LC‑MS workflows. The Y‑slit design offers an effective balance between needle accessibility and sealing performance for routine analytical applications.
Pre‑slit septa are commonly recommended for Waters® Alliance instruments, where smooth needle entry is critical for consistency. While the Y‑slit improves ease of penetration and targeting, it provides slightly reduced resealing compared to single‑slit designs. The blue polyethylene cap supports easy handling and workflow organization.
