The Endure Staining System is designed to produce precise, consistent H&E staining. Staining times in hematoxylin and eosin will depend on the use and the personal preference of the diagnosing physician. CDI has guidelines that will help establish a custom protocol for your specific needs. The Endure H&E System includes Hematoxylin, Eosin, Bluing and Clarifier (Aqueous or Alcoholic). Each component is analytically optimized for staining consistency and longevity.
