DURAN Wheaton Lined Aluminum Seal (224235-01)

DURAN Wheaton Lined Aluminum Seal (224235-01) PTFE/S/PTFE

The DURAN Wheaton Lined Aluminum Seal (224235-01) is an open-top crimp seal manufactured from natural aluminum and lined with a PTFE/S/PTFE (Polytetrafluoroethylene/Silicone/Polytetrafluoroethylene) composite. Designed for vials with an outer diameter of 11 mm, it delivers airtight sealing, superior chemical resistance, and multiple resealing capability.

The PTFE layers provide a completely inert surface that prevents sample interaction or adsorption, while the silicone core ensures excellent elastic recovery for repeated needle punctures. The open-top design allows direct syringe or septum access without compromising sterility or sample purity.

Engineered for high-precision use, the DURAN Wheaton Lined Aluminum Seal guarantees secure vial closure for volatile or reactive samples in analytical and pharmaceutical laboratories.
