In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down.
A distillation setup using a Liebig-type condenser (the tilted double-walled tube at the center). A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point. The vapor is then cooled as it goes through the inner tube of the condenser. There it becomes liquid again, and drips into the smaller collecting flask at right, immersed in a cooling bath. The two hoses connected to the condenser circulate water through the space between the inner and outer walls.

In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In doing so, the latent heat is released by the substance
