In the process of distillation vapors passing through the condenser tube are cooled and condensed by water flowing through condenser tube in the condenser unit of the apparatus. In almost all laboratories the water used for cooling the condenser tube is coming from the water supply tap near the wash basin. The precious water after circulating through the condenser tube is left into the drain as wastewater. It has been observed that about 40 liters of water is required for cooling for making 500 ml of distilled water. The water after cooling is generally left to go into the drain.

The following video has been prepared by me and is released by youtube. The video gives good information for those who want to learn about the traditional method of glass distillation and the modified Recycling Distillation Technique (Sharma, 2004) that saves gallons of water.
