1.5 Intended use
The Memmert waterbaths are intended for indirect tempering of samples or materials.
Water is meant to be used as the tempering medium. A wide variety of samples are
tempered in a range from approx. 5°C above room temperature to 100 °C. This can be
done in suitable vessels such as test tubes, Erlenmeyer asks etc., or if the sample to
be tempered is suitable, in direct contact with the tempering medium.
It is not possible to include all possible applications. Application is at the operator’s
discretion and under their responsibility.
Any other use is improper and may result in hazards and damage. The appliance is not
explosion-proof (does not comply with the German occupational health and safety regu-
lation VBG 24). The appliance may only be loaded with materials and substances which
cannot form any toxic or explosive vapours at the set temperature and which cannot
explode, burst or ignite. The appliance may not be used for the drying, evaporation and
burning-in of paints or similar materials, the solvents of which could form an explosive
mixture when combined with air. If there is any doubt as to the composition of materi-
als, they must not be loaded into the appliance. Potentially explosive gas-air mixtures
must not form, neither in the working chamber nor in the direct vicinity of the appliance.
1.6 Changes and alterations
No unauthorised changes or alterations may be made to the appliance. No parts may be
added or inserted which have not been approved by the manufacturer.
Unauthorised changes or alterations result in the CE declaration of conformity losing its
validity, and the appliance may no longer be operated.
The manufacturer is not liable for any damage, danger or injuries that result from un-
authorised changes or alterations, or from non-compliance with the provisions in this
manual.
