DURAN Wheaton Screw Cap (W240830)PP White, Solid Top 13-425

The DURAN Wheaton Screw Cap (W240830) PP White, Solid Top 13-425 autoclavable closure engineered for E-Z Ex-Traction vials with a 13-425 thread size. It features a PTFE/Silicone solid top liner, ensuring a tight and chemically inert seal that preserves sample purity and integrity in critical laboratory applications.

The DURAN Wheaton Screw Cap combines lightweight, heat-resistant polypropylene construction with the dual-layer PTFE/Silicone liner system. The PTFE face provides a non-reactive barrier against aggressive solvents and reagents, while the silicone backing offers elastic compression for leak-free performance and repeated use.

This cap is fully autoclavable and maintains its shape and mechanical stability under sterilization conditions. It is ideal for chromatography, sample storage, and pharmaceutical analysis where cleanliness and chemical compatibility are essential.
