How much time do we need to evaporate organic solvents in .

I agree with Sergey, there will be no problems with methanol and/or chloroform. 2 ml water need about 5-10 min at 30°C with our rotary vapors (5 mbar).

How to use a Rotary Evaporator

methanol: 64.7 o C: 5.0 o C: water: 100 o C: 34.0 o C: Since the flask is rotated during the evaporation process, the surface area is larger than normal which increases the evaporation rate significantly. The solvent is collected in a flask and can properly be disposed off afterwards (organic solvent waste). In addition, this method also avoids .

Any Rotovap Tips? : chemistry

the reason you spin on a rotovap is to increase the surface area exposed when evaporating, and disrupt the surface such that it doesn't bump. I rotovap at a speed fast enough to ensure the liquid in the flask is swirling, and that an even thin layer is exposed to the vacuum on each rotation. this varies based on flask size, and liquid viscosity. and in later stages how much compound I expect .
