1) Description
This SEPTA polyimide/silicone barrier is a perfect replacement when PTFE analytical barriers are not feasible in some laboratory environments. Because PFAs and polyfluoroalkyl compounds do not break down, they can accumulate in the environment and in the human body over time. There is growing evidence that exposure to PFAs can adversely affect human health. Therefore, regulatory bodies are increasingly legislation requiring more testing of materials to ensure they do not contain traces of PFAs or levels below legally permissible limits. Since PFAs are widely used in materials commonly used in chemical analytical instruments, such as PTFE, these polyimide/silicone barriers are a good option.
2) Applications
Polyimide/silicone Septa PFAS analysis
is a perfect replacement for PTFE, ensuring the required accuracy for fluoride-free determination.
It is applied to PFA detection, avoiding fluoride interference and maintaining sample purity.
The SEPTA polyimide/silicone organic solvent analyzer
offers high stability in organic solvent analysis and is suitable for liquid and gas chromatography.
Its fluorine-free design reduces solvent interaction and ensures analytical accuracy.
Environmental monitoring
applies to the analysis of environmental samples such as water and air quality, particularly the detection of fluorine-free environmental requirements.
It effectively avoids interference from substances like PFAs and ensures accurate detection of environmental pollutants.
Polyimide/silicone Septa biological sample analysis
ensures a fluoride-free test environment for the analysis of biological samples such as blood and urine.
It is applied to clinical diagnosis and biomarker detection to ensure that samples are not contaminated by septa.
3) Features
▶ High-Quality Material: Made of polyimide/silicon material, polyimide is a high-performance resin with excellent high-temperature resistance . It can maintain stable physical and chemical properties over a wide temperature range and is suitable for high-temperature operating conditions. Polyimide also has good radiation resistance and abrasion resistance, making it suitable for use in harsh environments.
▶ Fluorine-Free SEPTA: Using fluorine-free materials (such as PP, polyimide, etc.) to replace PTFE can effectively avoid this interference and ensure the accuracy of analytical results.
▶ Excellent Sealing Performance: The open cap, with its ribbed design, provides extra grip to ensure the cap is easily tightened and opened while maintaining an excellent seal.
▶ Double-Layer Buffer Design: Polyimide and silicone Septa combine the excellent high-temperature resistance of polyimide with the excellent sealing and elasticity of silicone for double sample protection.
