DURAN Wheaton Screw Cap (W240846)

DURAN Wheaton Screw Cap (W240846) PP White, Open Top

The DURAN Wheaton Screw Cap (W240846) is an autoclavable white polypropylene (PP) open-top closure designed for E-Z Ex-Traction vials with a 24-400 thread size. Equipped with a PTFE/Silicone liner, it ensures an airtight, chemically inert, and leakproof seal for analytical, chemical, and pharmaceutical laboratory applications.

The DURAN Wheaton Screw Cap combines lightweight, durable polypropylene construction with a dual-layer liner for maximum sealing performance. The PTFE face provides superior chemical resistance and prevents sample contamination, while the silicone backing delivers elastic compression for airtight resealability. The open-top design allows easy insertion of septa or syringe access for sampling, reagent addition, or sterile transfers.

Its autoclavable structure maintains stability under heat and pressure, ensuring long-term reliability for chromatography and precision sample-handling workflows.
