Eosin Y (yellowish)

Premium histology stains and reagents are designed to complement one another to provide optimum results, enabling greater control of slide presentation when used together.


  • Analytical chemistry standards and performance tests are applied to ensure consistency
  • Complementary use provides an excellent value for the cost


Each stain and reagent is chemically engineered to support the others, resulting in reliably consistent results from the first slide to the last


Eosin stains allow users to alter the intensity of the stain through varied staining times. The standard Eosin solution will result in a more lightly stained cytoplasm, and present with a more pastel appearance. The solution with phloxine will produce a redder color in the cytoplasm, particularly in connective tissue components.


All stains and reagents undergo performance tests and pass analytical chemistry standards.
