Mercury is a dangerous chemical substance that has extremely harmful effects on health and the environment, and various regulations have begun in recent years. The regulations regarding the purchase of mercury-containing products differ by affiliated organizations and companies, but a survey conducted by our company in 2020 found that the most common response was "it is necessary to choose products that contain as little mercury as possible," at 47%, while 19% responded that "products containing mercury cannot be purchased," resulting in a total of 66% of organizations having regulations in place. Recently, efforts towards sustainability have been increasingly emphasized. ↓↓ For more details on Merck's mercury-free technology, please see below.

To ensure accurate results, prevent false positives or false negatives, and avoid contamination, it is essential to carefully select reagents containing water when preparing liquid or solid media. Tap water may contain various impurities that can affect bacterial growth or cause errors in the prepared media. Since water is a major component of the media, the removal of these contaminants from water is crucial for media preparation. The recommended water quality for media preparation is detailed in ISO 11133:2014 ("Microbiology of food, animal feed and water — Preparation, production, storage and performance testing of culture media"). Additionally, ANNEX H discusses troubleshooting for media, citing the use of inappropriate quality of pure water as a cause of incorrect pH, color anomalies, formation of precipitates, and culture inhibition. This technical document explains the ISO 11133 standards and Merck's pure water production systems that meet these criteria.
