Silicone/PTFE (Polytetrafluoroethylene) septa, also known as silicone/PTFE liners or caps, are commonly used in laboratories and analytical chemistry for sealing sample vials or containers. These septa provide a secure and reliable seal to prevent sample evaporation or contamination.Silicone/PTFE septa are widely used in applications such as gas chromatography (GC), liquid chromatography (LC), headspace analysis, and sample storage. They are available in different sizes and configurations to fit specific vial or container types, ensuring a secure and reliable seal for various laboratory processes.
