Caps, Snap Top, with Red Rubber / PTFE Septa, fitted in smooth, polyethylene, Red Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. 100/PK.
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 in the septa.
The 9502C‑40CR Snap Caps are often selected by laboratories that prefer to eliminate silicone from the analytical pathway to reduce potential interference or compatibility concerns. The PTFE layer provides chemical resistance, while the red rubber backing supports effective sealing for routine workflows.
This configuration provides a cost‑effective alternative to silicone‑based septa, making it suitable for high‑volume laboratory use. The red polyethylene cap supports consistent identification and workflow organization in HPLC and LC‑MS environments.
