Mechanical cleaning and disinfection of the light guide
(washer-disinfector)
As an alternative, cleaning and disinfection can be
carried out mechanically. Information on the validated
procedure can be obtained from Ivoclar Vivadent AG.
Sterilization of the light guide
Thorough cleaning and disinfecting is imperative to
ensure that the subsequent sterilization is effective. Use
only autoclave sterilization for this purpose. The
sterilization time (exposure time at sterilization
temperature) is 4 minutes at 134 °C (273 °F); pressure
should be 2 bar (29 psi). Dry the sterilized light guide
using either the special drying program of your steam
autoclave or hot air. The light guide has been tested for
up to 200 sterilization cycles.
Checking the light guide
After that, check the light guide for damage. Hold it
against light. If individual segments appear black, glass
fibres are broken. If this is the case, replace the light
guide with a new one. If you can still see signs of
contamination on the light guide, the cleaning and
disinfecting procedure must be repeated.
Disposal
The curing light must not be disposed of as
normal houshold waste. Dispose
unserviceable batteries and curing lights
according to the corresponding legal
requirements in your country. Batteries must
not be incinerated.
