Nigrosine Stain Solution-10% – 125ml Packs

Nigrosine Stain Solution 10% is a classic particulate negative stain tailored for student practical work in microbiology and cytology. It offers an intuitive, accessible method for observing micro-structures without complex preparation protocols.

In school and college laboratory practicals, this solution is widely used for negative staining demonstrations. Because the acidic dye particles do not penetrate cell walls, the microorganisms remain clear against a dense, dark background, enabling students to accurately judge true bacterial morphology, capsule boundaries, and cellular arrangements.

This practical laboratory reagent is an essential teaching tool for secondary and tertiary educational laboratories. It simplifies microscopy sessions by eliminating distortion associated with heat fixation, ensuring positive learning outcomes.

Bottles must be stored tightly closed at ambient room temperature to prevent water evaporation and particulate clumping. Standard bench coats and gloves should be used by students to keep workspaces and hands free of black stain residues.
