Victoria blue Extra Pure
Victoria Blue Extra Pure is a high-purity, deep blue synthetic dye primarily used as a biological stain and textile dye. It exhibits strong affinity for acidic cellular components and is widely employed in microscopy, histology, and microbiology for staining applications. It dissolves readily in water and organic solvents, producing intense coloration with good stability. The Extra Pure grade ensures minimal impurities, making it suitable for analytical and research purposes. Handling requires standard chemical safety precautions due to its irritant potential. Storage in cool, dry, and protected conditions maintains product integrity.
