How to select a pump for rotary evaporation

Methylene chloride and pentane, do not require as deep of an end vacuum to evaporate as solvents such as acetonitrile, benzene, and chloroform. The removal of solvents with high boiling points, such as water, DMSO, DMF, and toluene requires a relatively deep end vacuum. You must ensure that the pump is capable of reaching an end vacuum deep enough to remove the target solvents efficiently.
