Overview
Deionized water is ultra-pure water that has had virtually all mineral ions removed through ion-exchange processes. Also known as demineralized water, this clear, colorless, and odorless liquid maintains a neutral pH of 7.0 and provides the highest purity standards required for critical laboratory, pharmaceutical, and manufacturing applications. With its molecular formula H₂O and CAS number 7732-18-5, deionized water serves as an essential reagent and solvent where the presence of dissolved minerals could interfere with processes or contaminate end products.
Key Applications
Deionized water serves multiple critical functions across various industries. In laboratory settings, it acts as a primary reagent for analytical procedures, solution preparation, and equipment cleaning where trace minerals could affect results. The pharmaceutical industry relies on deionized water for drug manufacturing, formulation processes, and equipment sterilization. Semiconductor manufacturing utilizes this ultra-pure water for wafer cleaning and etching processes where even minimal ionic contamination can damage sensitive components. Additionally, it serves as an ideal HPLC mobile phase component and diluent for various chemical processes.
Safety & Handling
Deionized water presents minimal safety hazards as it has no flash point or autoignition temperature. Standard laboratory safety practices should be followed, including wearing appropriate personal protective equipment such as safety glasses and lab coats when handling large quantities. Ensure adequate ventilation in work areas, though deionized water produces minimal vapor concerns. The primary safety consideration involves preventing contamination rather than exposure risks, as this ultra-pure water can leach ions from containers and surfaces upon contact.
Storage & Shelf Life
Store deionized water in clean, non-reactive containers such as high-grade plastic or glass vessels specifically designed for ultra-pure water storage. Maintain storage temperatures between 15-25°C and protect from direct sunlight and contamination sources. Avoid metal containers as deionized water can leach ions from metallic surfaces, compromising purity. The product should be used promptly after opening to maintain ionic purity, as exposure to air can gradually introduce contaminants. Keep containers tightly sealed and store away from dust, chemicals, and other potential contamination sources.
