Deionized Water
Original price was: $ 0.49.$ 0.38Current price is: $ 0.38.
Deionized Water (DI Water), also known as demineralized water, is highly purified water that has had almost all of its mineral ions (such as sodium, calcium, iron, copper, chloride, and sulfate) removed through ion exchange, reverse osmosis, or other purification methods. It is a clear, colorless, odorless liquid with extremely low electrical conductivity and is considered chemically pure. Deionized water is used in applications where water purity is critical, including pharmaceuticals, electronics, cosmetics, laboratory use, and various industrial processes. Its lack of minerals makes it highly reactive with contaminants, which makes it both useful and sensitive in technical applications.
