Crystal Violet Stain, Advanced is a high-quality, aqueous formulation used as the primary stain in the Gram staining procedure. This critical first step differentiates Gram-positive from Gram-negative bacteria based on cell wall structure.

Formulated for clarity and consistency, Hardy Diagnostics’ advanced Crystal Violet Stain ensures uniform dye penetration, resulting in crisp, reliable results across a wide range of specimen types. Its precision-balanced concentration minimizes overstaining and enhances contrast when paired with Gram’s iodine, decolorizer, and safranin counterstain.
