When using the following devices, observe without fail the preparation
instructions of the instrument manufacturer:
Ultrasonic
units
Maintenance appliances for hand pieces and angle pieces
Cleaning and disinfection devices (e.g. thermal disinfector)
Load the autoclave
Only if the autoclave is properly loaded can the sterilization be effective
and the drying deliver good results.
NOTICE:
Use perforated trays, such as the trays from MELAG. Only this way can
→
condensate run off. If you use closed materials or shell halves to bear
the items to be sterilized, you risk bad drying results. Please note that the
use of tray insertions made of paper can perhaps likewise lead to worse
drying results.
Wrapping
The correct use of suitable wrapping is important for the success of the
sterilization.
Warning!
Employ only packaging materials and -systems (sterile barrier
systems), which satisfy the DIN EN IS0 11607-1 Standard.
You can employ reusable rigid packaging such as standard tray cassettes
or soft packaging such as clear-plastic sterilization packages, paper bags,
sterilization paper, textiles, fleece.
Closed sterilization -
containers
Preferably use sterilization containers made of aluminium. Aluminium
conducts heat well and thus accelerates drying.
When using closed sterilization containers, observe the following
instructions for holding the
→
sterilizing materials:
Warning!
■
Closed sterilization containers must be equipped at least on one side
– possibly below – with perforations or valves.
Non-observance leads to insufficient steam penetration which could
make the sterilization ineffective. Furthermore the condensate
drainage is prevented, and bad drying results are the consequence.
This can ultimately lead to unsterile instruments and thereby to
endangering the health of the patient and the practice team.
The sterilization containers from MELAG satisfy all requirements according
to
→
DIN EN 868 for successful sterilization and drying. They are
perforated in the lid and floor and are equipped with disposable paper
filters.
Stack sterilization
containers
Stack on top of each other, if possible, only sterilization containers of the
same size and with respectively identical spacer feet, where the
→
condensate can run off on the side at the walls.
