How to use the air cooler shell pipea

Wash it before use, expand the upper end of the cooling pipe, connect it to the branch pipe of the flask with a rubber stopper that has been drilled, add the substance to be distilled into the distillation flask, and then use rubber at the water inlet (lower mouth) of the cooling pipe. The pipe is connected to the water source, and the other rubber pipe is connected to the upper port, which is convenient for cooling wastewater to flow out. The lower end of the cooling pipe is connected to the receiving bottle, and the receiving bottle is usually connected with an elbow pipe, so that the distillate can flow out vertically. After all the devices are installed, they are fixed on the shelf, and the cooling water source is first turned on, and then heated until the distillate boils. The steam along the inner core tube encounters the cooling water-cooled tube wall and condenses into droplets, which flow into the receiving bottle. pure substance.

Reflux cooling tube device (actually used as a concentration and purification device), which directly inserts the cooling tube into the conical flask through the rubber stopper, and the conical flask is filled with the distillate and solvent. After heating to boiling, the droplets cooled by the vapor rising to meet the cooling water will still drop back into the conical flask, so that a small amount of solvent contacts the dissolved substances for many times, which will not cause volatilization loss, but also play a role in full dissolution.
