The purpose of the condenser tube

It is used in distillation liquids or organic preparations, as condensation or reflux. Reflux unit and distillation unit are commonly used experimental devices for condenser tubes.

Scope of application: Use an air condenser when the steam temperature is greater than 140 degrees Celsius, and use a straight condenser when the temperature is less than 140 degrees Celsius.

Condensing tubes are usually used on flasks that are intended to be used in experiments under reflux or on distillation flasks when condensed liquids are to be collected. Condensation of the vapor occurs on the inner wall of the inner tube. The space enclosed by the inner and outer tubes provides the water running area with the function of absorbing steam heat and removing the heat. There is often a high water pressure at the water inlet. In order to prevent the water pipe from falling off, the plastic pipe should be tied with a pipe bundle. When used under reflux, a rubber stopper should be inserted into the glass tube at the lower end of the condenser tube so that it can be inserted into the mouth of the flask to receive the vapor evaporating upward in the flask.
