Product Overview
Nigrosin is a widely used synthetic dye in microbiology and histology laboratories, prized for its ability to provide high-contrast negative staining. This water-soluble, acidic dye does not penetrate cellular structures, making it ideal for outlining bacterial cells, yeast, and other microscopic specimens against a dark background. The laboratory-grade Nigrosin offered here is finely powdered, ensuring easy dissolution and consistent staining results. Its deep black color enhances visibility under the microscope, aiding in the study of cell morphology and bacterial capsules. The dye is compatible with standard staining protocols and can be used in conjunction with other stains like safranin or crystal violet for differential staining techniques. With a shelf life of up to 2 years when stored properly in a cool, dry place, this Nigrosin dye is a reliable choice for routine lab applications. The 25 gm pack size provides an ample supply for frequent use in educational and research settings.
