Additional Info:

Solid caps with liners are used when a secure, resealable closure is required for storage rather than repeated autosampler injections.

The 9504S‑05S‑W screw caps feature a silicone rubber/PTFE liner that provides an inert sealing surface with good resealing characteristics. This design allows 15 × 45 mm (4 mL) autosampler vials to be used as storage containers, helping maintain sample integrity during handling and storage.

The white polypropylene cap includes a knurled exterior for secure grip and consistent torque. Designed for standard 13‑425 thread vials, these caps provide dependable fit and sealing performance for laboratory storage workflows.
