Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. PTFE‑only septa are designed for applications requiring the highest level of chemical inertness with no elastomeric materials present.
The 9502C‑50CB Snap Caps feature pure PTFE septa with no silicone backing, eliminating potential sources of extractables, leachables, and background signal. This makes them ideal for sensitive analytical methods where sample purity and low interference are critical.
Because PTFE does not reseal after puncture, these caps are best suited for single injections or non‑volatile samples. The blue polyethylene cap supports easy handling and identification while maintaining compatibility with standard 11 mm, 12 × 32 mm autosampler vials used in HPLC and LC‑MS workflows.
