Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. PTFE‑only septa are engineered for applications requiring the highest level of chemical inertness without elastomeric materials.
The 9502C‑50CY‑M Snap Caps feature pure PTFE septa with no silicone backing, eliminating potential sources of extractables, leachables, and background interference. This makes them ideal for sensitive analytical methods where maintaining sample purity is critical in HPLC and LC‑MS workflows.
Because PTFE does not reseal after puncture, these caps are best suited for single injections or non‑volatile samples. The yellow polyethylene cap supports clear identification and efficient workflow organization while also providing cost and time savings in high‑volume laboratory operations.
