Preparing the sterilization material
Cleaning and disinfection must always have been performed before sterilization. Only in this way is it
possible to guarantee the subsequent sterilization of the Sterilization material. The materials used, the
cleaning fluid and treatment procedures used are of decisive significance.
Please observe the following information before loading:
u Clean, disinfect and dry the instruments before every sterilization.
u Comply with the specifications of the manufacturer’s cleaning and care information when treating the
sterilization material. Only so is it possible to guarantee correct cleaning and disinfection and subsequent sterilization.
u Never place the sterilization material together in blocks, as this will prevent heat equalization.
u Do not place the sterilization material on cellulose, as this can result in a heat build-up.
u Always pack the sterilization material in aluminium containers. Stainless steel is unsuitable due to its
reduced heat conductivity. Do not use any textiles, paper or polyamide film as packaging. This packaging is unsuitable for high sterilization temperatures.
Heißluftsterilisator beladen
Only when correctly loaded is effective sterilization and good drying possible. Ensure the following during
loading:
u Insert trays or standard tray cassettes in the chamber only with their appropriate mount.
u When loading, ensure that air can circulate around the instruments unhindered. Do not load the trays
or standard tray cassettes one-sided and do not stack the sterilized equipment.
