As the most used reagent in the laboratory, pure water is widely used in scientific research, testing, medicine, food and other fields, and its purity profoundly affects the final production and quality analysis results. Pure water plays a very important role, from ordinary glassware cleaning water to precision instrumental analysis water. Especially in analytical experiments, the quality of pure water even directly determines the authenticity and reproducibility of experimental results.
On February 25, Mr. Zong Qinghou, the founder and chairman of Wahaha Group, passed away due to illness. In the past few days, many netizens have remembered the founder of the national drink on social **, and the topic of Wahaha Lab Royal Water has rushed to the first place on the hot search list on Weibo.
Laymen should not know, but as an industry insider, 2 yuan a bottle of Wahaha mineral water is the hard currency of many laboratories, and it is the experimental water loved by scientific researchers, and many laboratories have been used for more than ten years.
The conductivity, pH value and other indicators of Wahaha pure water meet the standards of laboratory water. For example, its conductivity test result is 108 s cm, which is much lower than the standard for drinking purified water (10 s cm) and even reaches the laboratory water level (5 s cm). In 2022, in a live broadcast on CCTV, Wahaha staff randomly selected pure water products for testing, and the results showed that the conductivity, pH value and other results were within the standard range of bottled drinking purified water. This is also why Wahaha pure water is very popular in the industry.
Wahaha, Watsons and other bottled purified water belongs to the category of food and beverage in nature, and mostly follows the standard of drinking purified water in the "GB 19298-2014 National Food Safety Standard for Packaged Drinking Water", which requires that the water source of drinking pure water is GB 5749 natural water, and appropriate processing methods are used to remove products made of minerals. The main focus of product quality standards includes: sensory indicators, physical and chemical indicators, pollutant content, microbial content, and food additives.
