When you are unable to use PTFE as a liner – this polyimide/silicone lined closure is the perfect alternative. This new closure has a useable temperature range up to 130°C., while the liner performs well up to ten injections. The polyimide is amber translucent and the white silicone rubber is a high purity rubber composition resulting in low leachables.

Because Per- and Polyfluoroalkyl substances dont break down they can accumulate over time in the environment and in the human body. There is increasing evidence that exposure to PFAS can adversely affect human health. As a result, regulatory bodies are increasingly legislating that many materials should be tested to ensure that they contain no traces of PFAS or that the traces are below allowed legal limits. Because PFASare widely used in materials, such as PTFE, commonly used in chemical analysis consumables, these products are a great alternative.
