Hardy Diagnostics Safranin, for Gram Staining is a classic microbiological counterstain used in the Gram staining procedure to differentiate Gram-negative bacteria following crystal violet and iodine application. The Safranin solution provides a clear pink to red coloration of Gram-negative cells while Gram-positive organisms retain their dark violet appearance.

This 250ml aqueous formulation delivers consistent staining intensity and uniform results across routine microbiology, quality control, and educational laboratories. It is an essential reagent for accurate bacterial morphology and Gram reaction interpretation.
