Key Features

20 mm crimp-top magnetic caps: Steel or BiMetal design provides secure GC/GC-MS sealing; crimp fit minimizes evaporation, ideal for volatile samples.
UltraClean PTFE/silicone septa option: Low bleed with extremely low metal ions, extractables, and leachables for high sensitivity and selectivity.
High-temperature silicone septa: Withstands heating above 300 °C without softening or releasing volatiles, ensuring stable and reliable results.
Applications: Ideal for food, forensic, and high-precision GC analyses.
