7. Wait until the measuring cell is dry (stable density reading).
The time needed depends on the vapor pressure of your cleaning liquid 2
and the temperature of the measuring cell (Ethanol at 20 °C: approx. 5 min.,
Acetone at 20 °C: approx. 3 min.).
If the ambient humidity is larger than 90 % relative humidity, use a drying
cartridge (see Appendix C.1) to reduce the drying time.

14.2 Storing the Instrument
Clean and dry the measuring cell (see Chapter 14.1) before storing the instrument
for more than one day. Otherwise, algae may grow on the glass surface that are
difficult to remove.
For storage for less than one day, the measuring cell can be filled with deionized
water or the last cleaning liquid that has been injected. In case of syringe injection,
leave the syringe mounted to the injection adapter to prevent spillage of the liquid.
14.3 Cleaning the Instrument Housing and Touch
Screen
To clean the instrument housing or the touch screen, use a soft tissue that can be
wetted with ethanol or warm water, if necessary with some mild cleaning agent
added (pH < 10).
WARNING
Ethanol is a highly flammable liquid.
•
Make sure that all safety instructions regarding the use of flammable
liquids (see Chapter 2) are strictly followed.
