DURAN Wheaton Lined Aluminum Seal (224231-05)

DURAN Wheaton Lined Aluminum Seal (224231-05) Liner PTFE/S/PTFE

The DURAN Wheaton Lined Aluminum Seal (224231-05) is an open-top crimp seal made from natural aluminum and lined with a PTFE/S/PTFE composite. Designed for vials with an 11 mm outer diameter, this seal delivers exceptional chemical resistance, airtight sealing, and re-usability for sensitive analytical and pharmaceutical samples.

Its advanced PTFE/S/PTFE (polytetrafluoroethylene / silicone / polytetrafluoroethylene) sandwich structure combines the resilience of silicone with the chemical inertness of PTFE, providing a non-reactive, resealable surface that prevents sample contamination. The open-top configuration allows easy syringe or septum access while maintaining sterility and pressure integrity.

The DURAN Wheaton Lined Aluminum Seal is ideal for laboratories handling volatile, corrosive, or high-purity materials that demand uncompromised sealing performance.
