Ai SolventVap 5.3 Gallon/20L Rotary Evaporator w/ Motorized Lift

Rotary evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 130 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 processuch 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℃ (210℉) with PID temperature control stepping at 0.1℃ 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.
