Those are the "steam" and "fractional" varieties of this process.
An apparatus named for Kugelrohr performs one type of it over short paths. One type of this process exploits Raoult's law to increase or decrease the vapor pressure of the substance, and may be more useful than another type which produces better results when the number of theoretical plates are increased, but cannot separate azeotropes. Those are the "steam" and "fractional" varieties of this process. For 10 points, identify this lab procedure where pure vapors of a liquid are captured and condensed, which is used to obtain a pure liquid from a mixture.
