CUSTOM ITEM: Caps, Snap Top, with 1.3mm thick, Silicone Rubber / PTFE, ultra-clean Septa, fitted in smooth, soft polyethylene, Light 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 increases flexibility, making these caps easier to apply when working with large numbers of vials.
The 9502C‑S40‑B Snap Caps feature a 1.3 mm thick ultra‑clean silicone/PTFE septa designed for reduced extractables and bleed compared to standard septa. This makes them well suited for LC‑MS applications where minimizing background interference is critical to achieving high sensitivity and accurate results.
Because the caps are more pliable than standard snap caps, they may not seal as tightly and are best used with low‑volatility solvents. The light blue polyethylene cap supports easy identification and workflow organization while maintaining compatibility with demanding analytical environments.
