Additional Info:
Snap caps provide a fast, press‑fit sealing solution that simplifies vial preparation while maintaining consistent autosampler performance. The soft polyethylene construction offers increased flexibility, making these caps easier to apply—especially in high‑volume workflows.
The 9502C‑S08‑T Snap Caps feature butyl rubber / Tefzel septa, providing a cost‑effective balance of chemical resistance and performance suitable for most routine analytical applications. This septa type is a practical option for laboratories seeking dependable performance without premium material cost.
Because the soft polyethylene caps are more pliable, they are easier to place onto vials but may not provide the same sealing strength as more rigid cap designs. These caps are best used with low‑volatility solvents to maintain sample integrity. The natural transparent cap allows easy visibility and sample identification.
