Hardy Diagnostics Gram’s Decolorizer, Intermediate Strength (50% Alcohol / 50% Acetone) is a balanced reagent specifically formulated for use in the Gram staining procedure to differentiate between Gram-positive and Gram-negative bacteria.

This intermediate-strength formulation provides controlled and consistent decolorization, reducing the risk of over- or under-decolorizing — a common issue with higher-strength alcohols or acetone mixtures. It ensures accurate differentiation of cell wall structure, supporting reliable microbial identification in clinical, food, and environmental laboratories.

Recommended for use with stabilized iodine, this reagent complements Gram stain kits and individual reagents for laboratories performing high-volume or research-grade microbial analysis. Each bottle is produced under strict quality standards to ensure lot-to-lot consistency, reagent purity, and dependable staining performance.
