Suitable for PFAS testing.
When you cannot use PTFE as a liner - this polyimide/silicone-lined closure is the perfect alternative.
Because Per- and Polyfluoroalkyl substances don't break down, they can accumulate in the environment and the human body over time. 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 PFAS are widely used in materials, such as PTFE, commonly used in chemical analysis consumables, these products are a great alternative.
