1) Description
This polypropylene/silicon septa is a perfect replacement when PTFE analytical grade is not feasible in certain 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 polypropylene/silicon septa are a good option.
2) Applications
Polypropylene/silicone septa (PFAS) are
a perfect replacement for PTFE, ensuring accuracy in fluorine-free determination requirements.
They are applicable for PFA detection, avoiding fluoride interference and maintaining sample purity.
Polypropylene/silicone Septa organic solvent analyzers
offer high stability in organic solvent analysis and are suitable for liquid and gas chromatography.
The 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.
Polypropylene/silicone separator analysis
ensures a fluoride-free test environment for the analysis of biological samples such as blood and urine.
It is applicable for clinical diagnosis and biomarker detection to ensure that samples are not contaminated by septa.
3) Features
▶ High-quality material: Made of polypropylene/silicon material, polypropylene is a durable and chemically stable plastic, offering excellent resistance to a wide range of chemicals and solvents. It ensures low adsorption, making it ideal for applications requiring high purity and minimal contamination.
▶ SEPTA Fluorine-Free: 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: Septa polypropylene and silicone combine the strength and chemical stability of polypropylene with the excellent sealing and flexibility of silicone, providing enhanced sample protection and ensuring reliable performance in various analytical applications.
