Product Description
Buchi flask used rotary evaporation is most often and conveniently applied to separate low boiling solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure. However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation (azeotropic behavior), and a sufficient difference in boiling points at the chosen temperature and reduced pressure. Rotavapor Flasks are Pear Shaped Flasks available in size 25 ml. to 3000 ml
