DURAN Wheaton Screw Cap (W240824)

DURAN Wheaton Screw Cap (W240824) Phenolic Black, Solid Top

The DURAN Wheaton Screw Cap (W240824) is a solid-top black phenolic cap designed for E-Z Ex-Traction vials with a 22-400 thread size. It is autoclavable and equipped with a PTFE/Rubber liner, offering a tight, chemically inert, and reusable sealing solution for demanding laboratory applications.

The DURAN Wheaton Screw Cap combines the structural strength of phenolic resin with the flexibility and sealing efficiency of a dual-layer PTFE/Rubber liner. The PTFE face provides excellent resistance against solvents, acids, and reactive substances, while the rubber backing ensures a secure compressive seal for leak prevention. This design delivers long-term durability, even under high temperatures or repeated sterilization cycles.

Ideal for analytical, pharmaceutical, and chemical laboratories, this cap ensures consistent sealing performance, reliable chemical protection, and compliance with modern lab requirements.
