Rotary evaporator - zxc.wiki

A rotary evaporator consists of a heating bath, a steam pipe with standard ground joint, to the lower end of which the evaporation flask is attached, a condenser with a vacuum attachment and a receiving flask. The rotatable steam pipe is led through a shaft seal into the cooler at its upper end and can be set in rotation using a continuously adjustable motor.

May 08, 2020 In general, your bath temperature should be 20C higher than the boiling point of the substance you want to evaporate. And your coolant should be 20C or more lower than the vapor temperature. For example, if the boiling point of your substance is 40C, a bath temperature of 60C and coolant temperature of 20C should provide an optimal setup.

Xylene is highly flammable, so one must take extra care when igniting it. The appropriate temperature for burning xylene depends on how it is being incinerated. For fluidized bed incineration, aiming for a temperature range of 450 to 980 degrees Celsius is safest. Rotary kilns should aim for temperatures ranging from 820 to 1,600 degrees Celsius.
