Distilled water is used for a wide range of applications, including preparing buffers and reagents, pH solutions, and media preparation.] It's also used in clinical biochemistry, PCR, ion chromatography, spectrophotometry, electrophoresis, and general chemistry. Furthermore, it can be used for washing and rinsing glassware, as a pretreatment for Type I (ultrapure) water systems, and in protocols specifically requiring glass distilled water. Distilled water can also be used as feed to autoclaves, humidification, environmental chambers, water baths, and dishwashers
