DURAN Wheaton Lined Aluminum Seal (224231-01)

DURAN Wheaton Lined Aluminum Seal (224231-01) Line PTFE/S/PTFE

The DURAN Wheaton Lined Aluminum Seal (224231-01) is an open-top crimp-type seal designed for vials with an outer diameter (OD) of 11 mm. Constructed from natural aluminum and lined with a PTFE/S/PTFE composite, it delivers maximum chemical resistance and sealing integrity for high-purity analytical and pharmaceutical applications.

The unique PTFE/S/PTFE (polytetrafluoroethylene/silicone/polytetrafluoroethylene) configuration combines the elasticity of silicone with the chemical inertness of PTFE, ensuring zero sample interaction and outstanding resealability after multiple punctures. The open-top design enables easy syringe or septum access without compromising sample sterility.

Engineered for demanding laboratory environments, the DURAN Wheaton Lined Aluminum Seal ensures secure, contamination-free closure of vials containing reactive or sensitive substances.
