Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The red rubber / PTFE septa construction offers dependable sealing while avoiding silicone materials.
The 9502C‑40CB Snap Caps are often selected by laboratories that prefer to eliminate silicone from the septa to reduce potential interference or compatibility concerns. The PTFE layer provides chemical resistance, while the red rubber backing supports sealing for routine analytical workflows.
This configuration also provides a cost‑effective alternative to silicone‑based septa, making it suitable for high‑volume laboratories. The blue polyethylene cap allows easy handling and application while supporting organized workflows in HPLC and LC‑MS environments.
