5.2 Cleaning
Especially after a cell has broken or after a reagent accident, the photometer
should immediately be cleaned (see also Section 6.1 A
CTIONS IN THE CASE OF
A BROKEN CELL
).
NOTE
The housing components are made out of synthetic materials (ABS, PMMA
and PC). Thus, avoid contact with acetone, ethyl alcohol and similar deter-
gents that contain solvents. Remove any splashes immediately.
5.2.1 Cleaning the enclosure
Clean the photometer enclosure as follows:

If the housing surface is dirty, wipe it with a soft cloth and mild soapy water.

Remove any chemicals splashes as soon as possible.

For disinfection, you can use isopropanol for cleaning for a short time.
5.2.2 Cleaning the cell shaft
Normally, it is not required to clean the cell shaft routinely. Remove dust and
slight contamination with a moist, lint free cloth. Use isopropanol briefly to
remove persistent coatings (e.g. reagent remains). Especially clean the bot-
tom parts of the lateral surfaces of the rectangular cell shaft where the light
barriers for the automatic cell recognition are located.
If a cell has broken, the cell shaft has to be cleaned immediately.
To do so, proceed as described in Section 6.1.
