DURAN Wheaton Screw Cap (W240822)

DURAN Wheaton Screw Cap (W240822) Phenolic Black, Solid Top

The DURAN Wheaton Screw Cap (W240822) is a high-quality Phenolic Black, Solid Top closure engineered for E-Z Ex-Traction vials with a 15-425 thread size. It is autoclavable and fitted with a PTFE/Rubber liner, providing a secure, chemically inert, and airtight seal for precision analytical and pharmaceutical workflows.

The DURAN Wheaton Screw Cap combines the rigidity and heat resistance of phenolic resin with the dual-layer performance of a PTFE/Rubber liner. The PTFE surface ensures total chemical inertness against reactive samples and solvents, while the rubber backing delivers elastic compression for a tight, leak-free seal. This construction is ideal for autoclave sterilization and long-term sample storage under demanding conditions.

It provides consistent crimp performance, excellent resistance to organic solvents, and superior mechanical stability in analytical and chemical laboratories.
