away immediately! - In case of long-term ex-
posure, the lid surfaces are only conditional-
ly resistant to solvents!
• The painted surfaces and the control panel
are not resistant to xylene or acetone!
• For cleaning the instrument, do not use any
one of the following: alcohol, detergents

sive cleaning powders, solvents containing
xylene or acetone!
• To clean the lids, control panel and housing,

enter in contact with any of the electrical
connections or get into the interior of the in-

• Wash the tap water and reagent stations in
the dishwasher at a temperature of max. +65
°C. - Use a standard detergent for laboratory

At any rate avoid washing the stations at
higher temperatures (e. g. in industrial dis-
washers which run at a temperature of
+85 °C), as the stations may become de-
formed!
