Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The tri‑layer septa construction is engineered to improve cleanliness and reliability during injection, especially in demanding high‑throughput environments.
The 9502C‑20CG‑M Snap Caps feature a red PTFE / white silicone / red PTFE septa configuration originally designed for legacy autosampler systems such as Agilent 1050 instruments. This design enhances needle wiping during injection, helping remove residual sample and improve overall system cleanliness.
In addition to improved wiping performance, the multi‑layer septa provides modestly improved resealing compared to standard silicone/PTFE septa. The green polyethylene cap supports clear visual identification and workflow organization while maintaining ease of use in HPLC and LC‑MS applications.
