20L Vacuum Rotary Evaporator For Reclamation Of Solvents

Short Description:

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure.

Rotary evaporators are also used in molecular distillation for the preparation of distillates and extracts. Now rotary evaporators can also be designed for Industrial and production with equipped high-capacity flasks.
