DURAN Wheaton Screw Cap (240418)

DURAN Wheaton Screw Cap (240418) Phenolic Black, Solid Top

The DURAN Wheaton Screw Cap (240418) is a solid-top black phenolic cap designed for E-Z Ex-Traction vials with a 24-400 thread size. Featuring a PTFE/Rubber liner, it provides a reliable, chemically inert, and airtight seal ideal for laboratory, analytical, and pharmaceutical applications.

The DURAN Wheaton Screw Cap combines the rigidity and heat resistance of phenolic resin with the sealing performance of a dual-layer PTFE/Rubber liner. The PTFE surface offers excellent chemical resistance against acids, bases, and organic solvents, while the rubber backing provides elasticity and tight compression to prevent leaks.

This cap maintains its integrity under autoclaving and long-term use, making it suitable for chromatography, reagent storage, and sample containment in demanding environments.
