Is there any difference between pure water (ultra-pure water) and (secondary) distilled water?
1. Distilled Water:
The most commonly used pure water in laboratory ultrapure water machines, although the equipment is cheap, but extremely energy-consuming and water-consuming and slow, the application will gradually decrease. Distilled water can remove most of the contaminants in tap water, but volatile impurities such as carbon dioxide, ammonia, silica, and some organic matter cannot be removed. Fresh distilled water is sterile, but bacteria are prone to multiply after storage. In addition, the storage container is also very particular. If it is a non-inert substance, the ions and the shaping material of the container will precipitate to cause secondary pollution.
