Functional principle of a Rotavapor
®
evaporation
The Rotavapor
®
R-220 Pro offers efficient, 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 flask
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
