Description Back to Top
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 Spectrum are glass distilled, sub-micron filtered, and undergo rigorous specification testing to insure accurate, repeatable results.
