The 20mm Aluminium Crimp White & Beige PTFE/Silicone Cap Septa is designed for reliable sealing of 20mm headspace and serum vials. The beige rubber/white PTFE-silicone laminate combines the flexibility of rubber with the chemical inertness of PTFE, ensuring the PTFE surface remains in contact with the sample to minimize contamination and leaching. The aluminium crimp cap delivers a superior leak-proof, evaporation-resistant seal, making it ideal for headspace GC analysis, pharmaceutical testing, and long-term sample storage. A crimping tool is required for proper application.
