Ethos Biosciences Gram Stain, Decolorizer 75/25, 4x8oz, Ethos

75/25 Gram Decolorizer is a solvent blend designed for microbiology and general laboratory applications. Used as the decolorizing step in Gram staining procedures, it selectively removes the primary stain from gram-negative organisms while allowing gram-positive organisms to retain the crystal violet–iodine complex. The controlled 75/25 formulation provides consistent and reliable decolorization for accurate differentiation during microscopic evaluation. Ideal for routine diagnostic and research workflows, it supports dependable and reproducible Gram stain results. Supplied in chemically compatible containers, 75/25 Gram Decolorizer is suitable for clinical, research, and educational laboratory environments.
