Additional Info:
Screw caps provide a secure, threaded sealing solution that ensures consistent and leak‑resistant performance in both analytical and storage applications. The knurled polypropylene cap design allows for easy handling and controlled tightening to achieve reliable closure.
The 9504S‑08‑SP Screw Caps feature a solid top design with a butyl rubber / PTFE liner that provides an inert and dependable seal. The PTFE layer offers chemical resistance to protect sample integrity, while the butyl rubber backing delivers adequate resealing properties for repeated access.
These caps are commonly used to convert 15 × 45 mm, 4 mL autosampler vials into convenient storage bottles, offering a practical and cost‑effective solution for laboratories that require both short‑term storage and sample protection.
The black polypropylene cap supports identification and is also useful for light‑sensitive samples while maintaining compatibility with HPLC, LC‑MS, and GC laboratory workflows.
