Industrial 20L rotary evaporator with electric lift. Rotary evaporator (or Rotavapor/ Rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporator makes the material be rotated to thin film, under the constant temperature and negative pressure.
It really helps. Hi Rukman. 100 mbar and 40C seems a little aggressive. Following the rule of 20, if you are setting your bath to 40C, you should set your vacuum such that the boiling point ...

The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding it. It also assumes the compounds in the liquid are thermally sensitive; otherwise you could just boil the solvent out. A rotovap works by creating a vacuum in a rotating glass flask.
The rotavapor apparatus was modified such that the vacuum connection was replaced by an air pump with a controlled air flow. To reduce the variation of aging condition due to variation of the temperatures in the oil bath of the rotavapor apparatus, an insulated covering for the oil bath was constructed and used in this aging process.
The unique foam sensor detects foam and responds with a brief shot of air, which breaks down the foam without stopping distillation. Virtually unlimited choice of flasks. A laboratory rotary evaporator is not always available. But by using a flange adaptor, evaporating flasks with a capacity of 1, 2 or 3 L can be used on the Rotavapor R-220 Pro.
