Distillate

The collected liquid is the distillate. Simple distillation can also separate liquids when their boiling points are sufficiently different for one to be collected before much of the other evaporates.

Collect this liquid, the distillate, in a separate vessel. A thermometer near the outlet helps monitor the vapour temperature. Simple distillation can also separate two liquids when their boiling points are sufficiently far apart: the more volatile liquid vaporises first and is collected after condensation.

Heat the solution so the solvent vaporises; cool the vapour in a condenser and collect the liquid distillate. The dissolved solid remains in the flask. Thus salt water calls for crystallisation if you want salt crystals, but simple distillation if you want the water.
