Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The specialized tri-layer septa construction is engineered for applications requiring improved cleanliness and reliable sealing across high‑throughput environments.
The 9502C‑20CB‑M Snap Caps feature a red PTFE / white silicone / red PTFE septa configuration that was originally developed 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 smooth blue polyethylene cap allows easy handling and application, making these caps well suited for high‑volume HPLC and LC‑MS workflows where efficiency and performance are critical.
