What's the difference between condensation and rectificator?
Condensation
Definition:
(n.) The act or process of condensing or of being condensed; the state of being condensed.
(n.) The act or process of reducing, by depression of temperature or increase of pressure, etc., to another and denser form, as gas to the condition of a liquid or steam to water.
(n.) A rearrangement or concentration of the different constituents of one or more substances into a distinct and definite compound of greater complexity and molecular weight, often resulting in an increase of density, as the condensation of oxygen into ozone, or of acetone into mesitylene.

Rectificator
Definition:
(n.) That which rectifies or refines; esp., a part of a distilling apparatus in which the more volatile portions are separated from the less volatile by the process of evaporation and condensation; a rectifier.
