2 Safety
2 Safety
This apparatus has been built according to state-of-the-art
and recognised safety rules. Still, it can be associated with
risks and hazards:
• If the apparatus is operated by insufficiently trained
personnel.
• If the apparatus is not used properly.
2.1 Symbols
Stop
Information on hazards, which can lead to heavy material
damages, to severe or life-threatening injuries.
Warning
Information on hazards which can be harmful to your health
and lead to material damage.
Please note
Information, pointing to technical requirements. If these are
not complied with, disturbances, reduced economic efficiency
and product losses can result.
Warning
Surface temperature more than 60°C.
2.2. Requirements placed on operators
This apparatus can only be used by expert personnel or other
persons, who, because of their education or profession are
familiar with hazards, which can arise when this apparatus is
operated.
Personnel lacking this kind of training or persons, still being
trained, require thorough instructions. These operating
instructions are the basis for such training measures.
2.3 Proper use
The Rotavapor is not intended for activities with excess
pressure. Thus, you should make sure that no excess pressure
develops in the Rotavapor.
This apparatus has been designed and built for laboratories. It
is to be used for activities, associated with evaporating of
solvents.

BÜCHI Rotavapor R-200/205
It is used for:
• Distilling solvents
• Vaporising of solvents and suspensions
• Recrystallisation
• Synthesis and cleaning of fine chemicals
• Soxhlet extractions
In the case of drying powders, electrostatic charges can form.
Proper use of the apparatus includes caring for it and carefully
handling it in accordance with the instructions found in these
operating instructions.
The heating bath is the heating source for distillation, whereby
the heating medium must be water or heat carrier oil. (see
Chapter Heating bath). The Rotavapor/Rotary Evaporator can
only be operated with a heating bath.
2.4 Improper use
Applications not mentioned above are improper. Also,
applications, which do not comply with the technical data are
considered improper . The operator assumes sole risk for any
damages, attributed to such improper use.
Especially the following uses are not permitted:
• Use of the apparatus in rooms, which require protected
apparatuses.
• Calibration apparatus for other apparatuses.
• Determination of samples, which can explode or ignite
(example: explosives, etc.) due to shock, friction, heat or
spark formation.
• Work in excess pressure.
• Working with other water or oil baths other than the heating
bath B-490, especially the use of heating sources with
temperatures above 180°C (e.g. a Bunsen burner, etc.).
• Processing of hard, brittle materials (example: stones, soil
samples, etc.), which can lead to destruction of the
evaporating flask.
• 3 Kilogram in an evaporating flask is the maximum weight
you can use with the Büchi Rotavapor. If the evaporating
flask is overloaded the joint adapter or the flask could break.
