Cleaning

Especially after a cell has broken or after a reagents accident, the photometer
should immediately be cleaned (see also section 6.1 A
).
A BROKEN CELL
5.3.1

Cleaning the enclosure

CAUTION
The housing components are made out of synthetic materials (ABS,
PMMA and PC). Thus, avoid contact with acetone, ethyl alcohol and
similar detergents that contain solvents. Any splashes must be wiped
off immediately.
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.
5.3.2

Cleaning the cell shaft

CAUTION
The surface areas of the cell shaft are made of synthetic material (PPO/
PS, PMMA). Thus, avoid contact with acetone, ethyl alcohol and similar
detergents that contain solvents. Any splashes must be wiped off im-
mediately.
Note
If a cell has broken, the cell shaft has to be cleaned immediately. To do so,
proceed as described in section 6.1.
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.
