2 Safety
This chapter highlights out the safety concept of the instrument and contains general rules of behavior
and warnings from direct and indirect hazards concerning the use of the product.
For the users' safety, all safety instructions and safety messages in the individual chapters shall
be strictly observed and followed. Therefore, the manual must always be available to all persons
performing the tasks described herein.
2.1 User qualication
The instrument may only be used by laboratory personnel and other persons who on account of
training and professional experience know of the potential dangers that can develop when operating
the instrument.
Untrained personnel, or persons who are currently being trained, require careful supervision by a qual-
ied person. The present Operation Manual serves as a basis for training.
2.2 Proper use
The rotary evaporator has been designed for use in technical laboratories and in production. It is
authorized for use in applications that work with the evaporation and condensation of solvents.
• Evaporation of solvents and suspensions
• Synthesis and cleaning of rened chemicals
• Reactions under reux
• Recycling and concentration of solvents
• Re-crystallization
• Drying of powders and granulates
2.3 Improper use
Applications not mentioned in section 2.2 are considered to be improper. Applications which do not
comply with the technical data (see section 3 of this manual) are also considered to be improper.
The operator bears the sole risk for any damages or hazards caused by improper use!
The following uses are expressly forbidden:
• Use of the instrument in explosive environments
• The production and processing of materials that can cause spontaneous reactions (e.g. explosives;
metal hydrids or solvents that can form peroxides)
• Processing with explosive gas mixtures
• Working without the evaporating ask being immersed in the water bath (risk of breakage)
• The drying of hard, brittle materials (e.g., stones, soil samples) that might cause damage to the
receiving ask
• Shock-cooling of the evaporating ask and other glass parts
• Installation or use of the instrument in rooms, which require ex-protected instruments
• For safety reasons, only original spare parts must be used
• Using the ask handler installed on the heating bath to lift or lower an evaporating ask

4 Description of function
This chapter explains the basic working principle of the Rotavapor®R-220 Pro. It also shows how the
instrument is structured and provides a general functional description of its assemblies.
4.1 Functional principle of a Rotavapor®evaporation
The Rotavapor®R-220 Pro oers ecient, time saving single-stage distillations for small and medium
stage productional applications. The process is based on the evaporation and condensation of
solvents or drying of powders and pasty materials in a rotating evaporating ask.
Standard vacuum applications
Due to its sophisticated seal system a highly stable vacuum level can be reached in combination
with a vacuum controller and a vacuum pump. The vacuum also eliminates unwanted or hazardous
emissions of vapors during the process and serves as an important safety feature. The low pressure
decreases the boiling point of the medium inside the Rotavapor®. This allows to treat the product
gently at even higher evaporation performance compared to environmental pressure operation.
Special applications
• For the oxydation of sensitive products, the processing can take place under inert gas conditions

aEvaporation area
The solvent is heated by means of a heating bath. The turbulent mixing inside the rotating
evaporating ask results in an increased evaporation rate.
The drive unit oers a wide range of rotational speeds to perfectly match dierent evaporation
tasks. It also leads to an even mixing of the sample, thus preventing stationary overheating in
the ask. When drying powders or pasty materials, the rotation ensures smooth and
thorough drying.
bCooling area
The solvent vapor quickly enters the condenser. Here, the energy in the solvent vapor is
transferred to the cooling medium (mostly water), so that the solvent condenses.
cReceiving ask
The receiving ask collects the condensed solvent.
NOTE
For information about optimum distillation conditions see section 6, Operation.
