7.HOW TO ARRANGE THE INSTRUMENTS FOR THE
STERILIZING PROCESS
7.1 Standard sterilizing
Before being sterilized, the instruments must be cleaned to remove blood residues, incrustations,
foreign bodies, etc. These impurities can damage the items being sterilized, the autoclave components
and prevent the sterilizing process from being correctly carried out.
These instruments must be made of NON-ferrous material since they could damage the other
instruments or the autoclave itself.
To achieve perfect sterilizing, it is therefore important to proceed in the following way:
1. Rinse and brush the instruments under running water immediately after use to remove all deposits.
2. Place the instruments in the ultrasound machine with distilled water and detergent solution if
possible.
3. Thoroughly rinse the instruments in demineralized water to prevent scaling stains.
4. Dry the instruments to eliminate all water residues which could lead to oxidation.
5. Wash, rinse and dry the supplied trays and make sure that they are perfectly clean.
6. To ensure that packaged instruments are perfectly dried, we recommend use of support art. M9050
supplied as an optional.
7. If loose instruments must be sterilized, it is advisable to cover the trays with a paper or fabric
napkin to prevent direct contact with the tray surface: do not place the instruments straight on to the
trays.
8. Scissors and forceps should be slightly opened. Mirrors and containers should be placed upside
down for the sterilizing process.
9. It is advisable to keep the instruments separated from each other to achieve a better sterilizing
action. Overloading will impair the sterilizing process.
10. If packaged instruments must be sterilized on the trays, place the packets with their transparent side
downwards and do not overlap. The packets should not be too large. Drying will be difficult if their
edges overlap.
11. The machine can operate with a maximum 3 Kg load.
7.2 Sterilzing handpieces
1.
Carefully read the handpiece operation manual with particular attention to the part about sterilizing.
2.
Wrap the handpiece in the special sterilizing cloth.
3.
Place the wrapped handpiece on a NON-perforated tray to prevent spilt lubricating oil from
polluting the pipes of the autoclave.
4.
Proceed with a short cycle 121°C sterilizing program.
5.
Remember to immediately remove the handpiece from the autoclave at the end of the sterilizing
process.
6.
It is inadvisable to sterilize handpieces using the night cycle.
It is essential to place a chemical indicator in the autoclave on each cycle, to ensure that the sterilizing
process has taken place correctly
