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).
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 .

A rotary evaporator (Rotovap) is a piece of machinery or equipment used in the creation of some cannabis concentrates. A rotary evaporator evaporates and recovers pricey ethanol from ethanol-extracted concentrates. Rotary evaporators are one of the key steps in creating butane hash oil (BHO) and other cannabis concentrates.

Rotary evaporator (also called "rotavap") are used to remove solvents from reaction mixtures and can accommodate volumes as large as 3 liters. They are found in almost every organic laboratory, since they allow performing this task very quickly. A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish.

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 .
