List of Disinfection/Sterilization Methods
CAUTION: When sterilizing the guard bowl unit by
high pressure steam, wear protective clothing like
gloves and take care not to get burned.
CAUTION: All of the components of the guard bowl
are autoclaveable. Each component must be
sterilized separately.
CAUTION: If the bowl lid, rotor and guard bowl are
placed in the same container for disinfection, they
may be deteriorated faster (dissimilar metal
corrosion). It is recommended to disinfect them
separately.
