DURAN Wheaton Screw Cap (W240832)

DURAN Wheaton Screw Cap (W240832) PP White, Solid Top

The DURAN Wheaton Screw Cap (W240832) is a solid-top white polypropylene (PP) closure designed for E-Z Ex-Traction vials with a 15-425 thread size. It features a PTFE/Silicone liner, offering excellent chemical resistance, flexibility, and resealability for laboratory and pharmaceutical use.

The DURAN Wheaton Screw Cap combines the durability and heat stability of polypropylene with the dual-layer protection of a PTFE-faced silicone liner. The PTFE layer provides a chemically inert barrier against solvents and reactive compounds, while the silicone backing ensures airtight compression and resealability. This construction maintains sample integrity and prevents leakage even under repeated handling or autoclave sterilization.

Ideal for chromatography, sample preparation, reagent storage, and sterile operations, this cap ensures long-term protection and compatibility with a wide range of laboratory chemicals.
