Catalog Number - 9502C-41S-M

The 9502C-41S-M BASIK Crimp Caps are engineered for sensitive chromatographic applications, featuring 0.05" thick silicone rubber/PTFE ultra‑low bleed septa to reduce siloxane background while maintaining excellent sealing and resealing performance.

Designed for 11 mm crimp‑top and snap‑top, 12 × 32 mm autosampler vials, these caps provide a secure, consistent seal, making them ideal for GC and HPLC workflows where low background interference and high throughput are required.

Supplied in a 1000 count case, these caps are optimized for laboratories running large sample batches and extended sequences.
