Acid Red 33 is a synthetic azo dye used as a stain and analytical indicator in laboratory and industrial applications. It produces a vivid red coloration and is commonly used for pH indication, biological staining, and textile dyeing. Its water-soluble powder form allows preparation of fresh solutions for reliable and reproducible results.

Field Stain A is a biological staining reagent formulated primarily with eosin Y (acid dye) dissolved in methanol. It is part of the Field’s Stain system (A & B), a rapid staining method widely used for malaria parasite detection and hematological studies. In powdered form, it contains the dye component used for preparing Field Stain A solution.

Jenner Stain is a dye mixture primarily used in hematology for the staining of blood smears. It is composed of methylene blue and eosin, providing a clear distinction between different cellular components, such as nuclei and cytoplasm. 

Bromocresol Purple (BCP) is a sulfonphthalein dye commonly used as a pH indicator, biological stain, and analytical reagent. It is especially useful for detecting pH changes near neutrality and in clinical chemistry applications.

 M Cresol Purple (meta-Cresol Purple, also known as Cresol Red) is a sulfonphthalein dye widely used as a pH indicator and spectrophotometric reagent. It is especially useful for monitoring pH changes in near-neutral to alkaline ranges and is also applied in clinical diagnostics and oceanography

Calcon is a complexometric and pH-sensitive azo dye used as a carboxylic acid indicator in analytical chemistry. It is primarily applied in titrations, water hardness determination, and metal ion analysis, where it forms distinct color complexes with metal ions or changes color in response to acidic functional groups.
