Condensers are equipments widely used to change the state of any substance from gaseous to liquid state. These are utilized in the procedures where organic liquids are changed into the state of gas through the process of heating. They are employed in training, research, or laboratory to pass a vapor flow over cooled chamber. They are designed in the form of concentric glass tubes with an inner one to let the hot gases pass, and the outer one part to make the cooling fluid passes. This process reduces the temperature of gas in the inner surface and let the process of condensation takes place.
