Gram’s Iodine Solution is a key reagent used in microbiology for Gram staining — the most common method to differentiate bacterial species. It acts as a mordant that helps fix the crystal violet dye on Gram-positive bacteria, making cell identification clearer under a microscope. This ready-to-use solution is ideal for laboratories, research centers, and educational institutions across Bangladesh. Supplied and quality-checked by Labtex Bangladesh to ensure reliable lab performance.
