CUSTOM ITEM: Caps, Snap Top, with 1.00mm thick, White Silicone Rubber / Blue PTFE Pre-Slit (X Shape) Septa, fitted in smooth, soft 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 consistent autosampler performance. The soft polyethylene construction offers increased flexibility, making these caps easier to apply, especially in high‑throughput workflows.

The 9502C‑S30‑B Snap Caps feature a 1.0 mm thick silicone/PTFE septa with an X‑shape pre‑slit design. This configuration increases the needle strike area, improving alignment and reducing penetration resistance while maintaining chemical resistance and dependable performance for HPLC and LC‑MS applications.

Because the caps are more pliable than standard snap caps, they may not seal as tightly in high‑volatility conditions. The X‑slit design further enhances ease of penetration but provides slightly reduced resealing compared to non‑slit septa. These caps are best used with low‑volatility solvents. The blue cap supports easy identification and workflow organization.
