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 ...
