UL/CSA Rotary Evaporators

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate “low boiling” solvents such as n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure. Careful ...

• The condenser could be overloaded since the evaporation rate will exceed the condensation capacity. Cannabis extracts require lower water bath temperatures (≈40 degrees Celsius). Oil baths can hold a higher temperature range than water baths. • Water baths topping out around 95 degrees Celsius, oil baths going up to 180 degrees Celsius (in
