Product Overview

Water, HPLC Grade

Molecular Formula: H₂O

CAS Number: 7732-18-5

Molecular Weight: 18.02

Water, HPLC Grade, is used in most HPLC mobile phases and in sample preparation. Because it dissolves most substances and is nontoxic, it is known as a Universal Solvent. To be used for HPLC analysis, it must conform to the highest purity standards. All HPLC and Ultra-pure solvents offered by ScienceLab are glass distilled, sub-micron filtered, and undergo rigorous specification testing to insure accurate, repeatable results.

Synonyms: Deionized Water
