Caps, Snap Top, with Red Rubber / PTFE Septa, fitted in smooth, polyethylene, Blue Caps. For use with 11mm, 12x32mm Snap Top autosampler vials. MICROSOLV Brand. 1000/CS.
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 eliminating silicone materials from the sample contact pathway.
The 9502C‑40CY‑M Snap Caps are often selected by laboratories that prefer to avoid silicone due to potential interference or compatibility concerns. The PTFE layer provides chemical resistance, while the red rubber backing supports effective sealing for routine analytical workflows.
This configuration provides a cost‑effective alternative to silicone‑based septa, making it well suited for high‑volume laboratories. The yellow polyethylene cap supports clear identification and efficient color‑coding for organized HPLC and LC‑MS workflows.
