Caps, Snap Top, with 1.00mm thick, White Silicone Rubber / Red PTFE Pre-Slit (Y Shape) Septa, fitted in smooth, soft polyethylene, Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. 100/PK.

Additional Info:

Provide improved sealing and easy handling with soft snap caps designed for efficient autosampler workflows and repeated injections.

9502C-S34-B caps are manufactured from soft polyethylene, making them more pliable than standard snap caps. This allows easier placement on vials, especially when working with large sample batches. The flexibility of the cap design makes them a popular choice for high‑throughput environments where speed and ease of use are important.

The white silicone / red PTFE septa feature a 1.00 mm thickness and a pre‑slit Y‑shape design. The Y‑slit offers a larger target area for autosampler needles, enabling easier penetration while maintaining better resealing performance compared to X‑slit designs. The thicker septa improves overall sealing integrity, while the PTFE surface provides chemical resistance and the silicone core supports resealability.
