Naphthol Green B is a synthetic dye used as a stain and analytical indicator in laboratory applications. It produces a green coloration in solution and is commonly used for biological staining, histological studies, and as a complexometric indicator.

Rose Bengal is a xanthene dye widely used as a stain indicator in microbiology, histology, and analytical applications. It exhibits a bright red to pink color and is highly soluble in water, making it ideal for staining cells, tissues, or detecting specific chemical reactions. Its vivid color allows for easy visualization under a microscope or in solution-based assays.

Methylthymol Blue Complexone is a complexometric metallochromic indicator widely used for titrations of metal ions, especially calcium, magnesium, and other divalent cations. It forms colored complexes with metal ions, allowing precise detection of titration endpoints in EDTA or other chelating agent titrations.
