Our Astral Diagnostics brand offers a broad spectrum of hematoxylin formulations. Traditional regressive stain solutions such as Harris Hematoxylin Alum are complemented by specially-formulated progressive stain solutions producing staining intensities characteristic of Gill Hematoxylins.

Whether used in histology for hematoxylin and eosin staining requirements or in cytology to demonstrate cell nuceli, the wide variety of hematoxylin formulations and packaging configurations offer the user a selection of products that can be used either progressively or regressively in diagnostic analysis.
