PTFE (polytetrafluoroethylene) silicon vials, also known as PTFE-lined silicon vials, are specialized containers commonly used in pharmaceutical and laboratory settings. These vials are designed to provide a high level of chemical resistance and inertness, making them suitable for storing and transporting sensitive or reactive substances.TFE silicon vials are commonly used for storing and transporting pharmaceutical drugs, particularly those that are sensitive to interactions with container materials.
