  • Sterilisation of products in synthetic material

    • Before you sterilize a product, the product has to be free of contamination or waste reminders. You also have to delete all stoppers or lids during the sterilization process.

    Synthetic material Autoclavable at 121°C Gas sterilization (ethylene oxid) Dry sterilization at 160°C Chemical sterilization (in formalin) Gammasterilization
