Product Overview

Water Deionized (CAS No. 7732-18-5) is water that has undergone treatment intended to reduce dissolved ionic species through deionisation processes. Removal of cationic and anionic contaminants makes deionised water useful for reagent preparation, rinsing and general laboratory operations where ordinary tap-water ions would interfere. Deionisation primarily addresses ionic contamination and does not by itself establish sterility, low organic carbon or chromatographic-grade performance.

Deionized Water is intended for routine laboratory solution preparation, dilution, washing, rinsing and general aqueous chemistry requiring reduced ionic background. Its purification by ion removal makes it particularly useful where dissolved mineral ions could interfere with reagent systems or laboratory processes.

Typical Applications

• Preparation of routine laboratory solutions.
• Dilution of reagents and samples.
• Final rinsing of laboratory glassware and equipment.
• General inorganic and solution chemistry.
• Preparation of buffers and washing solutions.
• Laboratory processes requiring reduced ionic background.

Common Synonyms

• Deionised water
• DI water
• Aqua
• Dihydrogen monoxide
• Dihydrogen oxide
• Oxidane

Storage Conditions

Keep tightly closed and protect from recontamination by atmospheric, container-derived and laboratory ionic species. Maintain clean dispensing systems because deionised water can readily acquire contaminants after purification.
