Cleaning the instruments
Clean all instruments thoroughly prior to sterilization.
If possible, clean instruments immediately after use; always follow the instrument manufacturer ‘s instructions.
Remove all traces of disinfectants and detergents.
Rinse and dry carefully all instruments.
Lubricate dental handpieces after cleaning and prior to sterilization in accordance with the manufacturer’s instructions.
Preparing the trays
Do not overload the chamber; adhere to the maximum load weight limits (see cycle program table; the available sterilization cycles).
Always use the chamber rack to allow adequate steam circulation.
Place pouched items on trays with the paper side facing up.
Do not overload trays. The weight must be spread as evenly as possible among the trays.
Place cassettes in the vertical position (if possible) to enhance drying.
Place empty vessels or non-perforated trays upside down to prevent accumulation of water.
Items made from different materials (stainless steel, carbon steel, aluminum, etc.) must be placed on separate trays or
wrapped/pouched.
If the instruments are manufactured from carbon steel, paper should be placed between them and the trays to avoid rusty spots.
Sterilize hinged instruments (e.g., forceps, extraction pliers, etc.) in the open position.
Wrap items with porous wrapping materials to facilitate steam penetration and drying (e.g. sterilization bags for autoclaves).
The instruments must be carefully rinsed and dried prior to sterilization.
Any residual of chemicals (like cleaning and disinfection products), could affect the purity of the steam and consequently the
whole sterilization process, and could seriously damage the sterilizer.
The manufacturer’s warranty is void in case of damage caused by chemicals.
