Clean the Glass Doors

Some precautions in the cleaning and care of the environmental chamber glass doors:
Moisture leaches alkaline materials (sodium, Na) from the surface of the glass.
Evaporation of the moisture concentrates the alkaline and may produce a white staining or
clouding of the glass surface. Cleaning chemicals with a pH above 9 accelerate the
corrosion process. Therefore, it is very important to rinse and dry the glass doors after
cleaning.
There is no simple method for repairing corroded glass. In most cases, the glass
must be replaced.
Electrical shock
Contact with current-carrying components may cause a lethal electric shock.
Prior to cleaning and disinfection work, disconnect the device from the power supply!
Turn the device off using the power switch.

Unplug the power connector and protect it against accidental reconnection.

Make sure the device is de-energized.

Health hazard
The surfaces of the workspace may be contaminated. Contact with contaminated
cleaning liquids may cause infections. Disinfectants may contain harmful
substances.

regulations!
