DURAN Wheaton Screw Cap (W240836)

DURAN Wheaton Screw Cap (W240836) PP White, Solid Top

The DURAN Wheaton Screw Cap (W240836) is a solid-top white polypropylene (PP) closure designed for E-Z Ex-Traction vials with a 24-400 thread size. It is autoclavable and features a PTFE/Silicone liner, providing reliable, airtight, and chemically resistant sealing for laboratory, analytical, and pharmaceutical use.

The DURAN Wheaton Screw Cap offers a combination of heat-resistant polypropylene material and a dual-layer liner that ensures superior protection and sealing performance. The PTFE surface provides excellent chemical inertness, preventing sample contamination, while the silicone backing maintains elastic compression for a leak-free seal even after multiple uses or sterilization cycles.

This cap is ideal for chromatography, reagent storage, and biotechnological research where sample purity and closure integrity are critical.
