2 Safety
2.4
Unauthorized Use
Any use other than those indicated above, and any use that
is not in conformity with the Technical Data is considered to
be misuse. The operator himself bears sole responsibility for
all damage or injuries arising from any such use.
The following applications in particular are strictly forbidden:
•
The production and processing of materials that can cause
spontaneous reactions, e.g., explosives;
•
Working without the evaporation flask being immersed in
the water bath (risk of breakage);
•
The drying of hard, brittle materials (e.g., stones, soil sam-
ples) that might cause damage to the receiving flask;
•
Sudden shock-cooling of the evaporating flask.
The Rotavapor R-220 is not intended for work done under
overpressures.
2.5
Basic Dangers
Basic dangers arise when working with the following:
•
The hot water or oil bath (risk of being scalded);
•
Contaminated solvents that produce residues from distilla-
tion which could cause spontaneous reactions (e.g., metal
hydrides);
•
Solvents that can produce peroxides (risk of explosions);
•
Mixtures with unknown compositions or contamination;
•
Damaged glassware;
•
Electrostatic charges while working, e.g., during the trans-
fer of combustible solutions and while drying powders;
•
Temperatures of coolants that lie below the freezing point
of the distillate (A clogging of the distillate cooler due to
freezing out can result in too great an overpressure).
2.6
Safety Precautions
All regional and local laws and regulations must be observed.
The Rotavapor has been grounded internally to dissipate any
electrostatic charges on it.
