14 / 18 319300-9231-000-AddGA01-GB-240320
Action 1. Remove the measuring prisms from the tonometer holder (a)
and clean under running water (drinking water quality) (recom-
mended time 60 seconds).
2. Clean the measuring body with a pH-neutral cleaning agent
until no more dirt is visible.
3. The cleaning agent must then be rinsed off well under running
water (drinking water quality)! (recommended time 60 seconds)
(b).
4. Dry the measuring prisms with a lint-free disposable cloth (c).
5. Perform visual checks for cleanliness and perfect working
condition.
6. Place the cleaned measuring prisms in the Desinset plastic tray
(d).
3.2 Disinfection steps
We recommend the use of a validated disinfectant (see chapter
Validated cleaning and disinfecting agents [
}
8]).
The operator accepts all liability for the use of other cleaning
agents.
The maximum, material-compatible exposure time for the disin-
fectant is 60 minutes.
Action 1. Take the measuring prisms to be disinfected out of the plastic
tray and place them on the lower tray (e) of a clean, disinfected
Desinset plastic insert.
NOTE! The measuring prisms must not overlap.
2. Add at least 600 ml of disinfectant solution (f), so that the
lower tray is completely immersed.
3. Place the disinfectant in one of the two Desinset measuring
beakers.
WARNING! All measuring prisms must be completely
immersed in the disinfectant solution. As the measuring
prisms tend to float in the solution, they must always be
placed in the lower tray of the Desinset insert.
4. Allow the disinfectant sufficient time to work as specified in the
disinfectant manufacturer’s instructions (g). The maximum,
material-compatible exposure time for the disinfectant is 60
minutes.
5. Once the exposure time has expired, remove the plastic insert
with the measuring prisms, allow it to drip dry (h) and then
place it in the other clean and disinfected measuring beaker.
The disinfectant must be replaced as follows:
• When visibly soiled.
• Once a day or as specified by the manufacturer.
