Deionized Water

Product Overview

Deionized Water (DI water), also known as Demineralized Water, is a high-purity solvent that has undergone extensive ion-exchange processing to remove dissolved mineral ions such as sodium, calcium, iron, and copper. This treatment results in a low-conductivity aqueous medium essential for industrial applications where ionic interference causes scaling, corrosion, or contamination. Supplied as a clear, colorless, and odorless liquid, our Deionized Water is optimized for consistency in manufacturing, cooling systems, and analytical laboratories.

To ensure performance, this product is maintained under controlled conditions to prevent atmospheric recontamination. It is the standard choice for applications requiring chemical neutrality and low total dissolved solids (TDS). From serving as a reliable chromatography mobile phase to preventing mineral deposits in industrial machinery, Alliance Chemical Deionized Water offers the strict lot-to-lot consistency required for process integrity.

Safety & Handling

Deionized Water is a non-hazardous material suitable for standard storage and transport. To maintain high purity, store in tightly sealed containers made of HDPE, polypropylene, or glass. Keep containers closed when not in use to prevent absorption of carbon dioxide and other atmospheric contaminants which can increase conductivity.

This product is not regulated as a hazardous material for transport (Non-Hazmat). While safe for handling, standard industrial hygiene practices should be observed. In the event of spills, the liquid presents a slip hazard. Refer to the Safety Data Sheet (SDS) for complete details.
