High -level disinfection
The washer-disinfector cleans items,
and in the disinfection program,
simultaneously thermally disinfects at
93°C/200°F.
Areas of effectiveness are physical
removal or thermal inactivation of
vegetative bacteria including
mycobacteria, fungi, fungal spores and
viruses. These catergories include the
Mycobacterium tuberculosis and the
Enterococcus faecium.
Important: Only the program labelled
"disinfection" disinfects! Only use this
program when handling contaminated
items. All other programs are designed
to clean items without disinfecting.
The washer-disinfector achieves
high-level disinfection as defined by
the Spaulding categorization.
The Spaulding category high-level
disinfection is the same type of means
as in the sterilant category except that
the use pattern is different. The sterilant
is used as a high-level disinfectant by
e.g. reducing the exposure time within
its effective range of tuberculocidal,
virucidal and bactericidal action.
Description of the machine
Instruments suitable for processing
in the washer-disinfector
In general, only high quality stainless
steel items are suitable for processing
in the washer-disinfector. All items to be
cleaned and disinfected in the
washer-disinfector should have the
following properties:
– heat resistance to a temperature of
95°C/203°F
– corrosion resistance in the presence
of heat and alkalinity.
The heat retention capacity of stainless
steel allows for fast drying. Plastic has a
lower heat retention capacity, thus
requiring a longer drying time. In this
case, a slightly extended waiting period
of 5-15 minutes may be necessary after
the disinfection cycle.
Aluminum items may discolour during
the cleaning process. Aluminum has
only a limited suitability for processing
in the washer-disinfector.
Carbon steel and chrome-plated items
may corrode during the cleaning
process. Processing these types of
items in the washer-disinfector is NOT
recommended.
Hand pieces, drill bits, grinders, root
canal instruments or other rotating
items are not suitable for the
washer-disinfector. Do not process
them in the washer-disinfector.
