Rotary evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds
from 10 to 180 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over
the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating
from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under
vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process
much more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system,
which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation.
Digital water bath operates from ambient temperature to 99°C (210°F) with PID temperature control stepping at 0.1°C
increments. Heating coils are located directly inside the pan for the most efficient heating possible. A built-in overheat
protector will shut down power, should the controller fail.
Standard Glassware Set includes 1.32 gallon (5 liters) round-bottomed evaporating flask, 0.79 gallon (3 liters)
round-bottomed receiving flask, and vertical condenser. Rotary evaporators with vertical glass condenser for are
great for distillation of solvents with higher boiling points.
