Cleaning the enclosure

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.
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

NOTE
The surface areas of the cell shaft are made of synthetic material (PPO/PS,
PMMA). Thus, avoid contact with acetone, ethyl alcohol and similar deter-
gents that contain solvents. Remove any splashes immediately.
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.
