The 11mm Aluminium Crimp Cap PTFE/Silicone Red & White Septa is designed for secure sealing of chromatography vials. The red rubber/white PTFE-faced silicone septum combines the flexibility of silicone with the chemical inertness of PTFE, ensuring the sample only contacts the PTFE surface to minimize contamination and leaching. The aluminium crimp cap provides a superior leak-proof and evaporation-resistant seal compared to screw caps, making it ideal for gas chromatography and long-term storage applications. A crimping tool is required for proper sealing.
