Product Description :Eosin (Spirit Soluble)

Eosin (Spirit Soluble), chemically recognized as Eosin Y (Acid Red 87), is an acidic xanthene dye specially formulated to dissolve in ethanol or other spirit-based solvents. This makes it ideal for alcohol-based staining techniques commonly used in rapid tissue staining, dehydration stages, and cytological procedures.

Unlike water-soluble Eosin, this spirit-soluble variant provides faster penetration, rapid staining, and enhanced differentiation of tissue elements. It produces bright red to pink coloration on cytoplasm, muscle fibers, connective tissues, and extracellular matrix components—essential for microscopic visualization and diagnostic interpretation.

Manufactured under Loba India’s rigorous analytical-grade and biological-grade quality standards, this dye ensures uniformity, purity, and high staining intensity. Laboratories across Bangladesh—particularly histopathology, cytology, and medical diagnostic centers—prefer Eosin (Spirit Soluble) due to its unmatched consistency and performance.

Bright Scientific ensures safe handling, proper storage, and reliable nationwide delivery of this sensitive biological stain.
