6 Sterilization
Preparing the sterilization material
Cleaning and disinfection must always have been performed correctly and appropriately before steriliza-
tion. Only in this way is it possible to guarantee the subsequent sterilization of the sterilization material.
The materials used, cleaning agents and reprocessing procedure are of decisive significance.
Please comply with the the following specifications before loading:
uClean, disinfect and dry the instruments before every sterilization.
uComply with the specifications of the manufacturer’s cleaning and care information when reprocessing
the sterilization material. Only in this way is it possible to guarantee correct cleaning and disinfection
and subsequent sterilization.
uNever place the sterilization material together in blocks, as this will prevent heat equalization.
uDo not place the sterilization material on cellulose, as this can result in a heat build-up.
uUnwrapped sterilized equipment looses its sterility upon contact with the ambient air. If you plan to
store your instruments in a sterile fashion, wrap them in a suitable packaging before sterilization.
uAlways 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.
Loading the dry-heat sterilizer
Effective sterilization and successful drying is only possible if the hot air sterilizer is loaded correctly.
Ensure the following during loading:
uInsert trays or standard tray cassettes in the sterilization chamber only with their appropriate mount.
uWhen 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 sterilization material.
