Clarifier™ 2 is an aqueous glacial acetic acid rinse designed to eliminate background staining sometimes caused by excessive adhesives in the water bath such as gelatin. Clarifier™ 2 selectively removes hematoxylin staining from excess adhesive without affecting nuclear staining. This product is only effective with progressive staining an should not be used with regressive stains. Clarifier 2 was designed to be used in histology only. Clarifier™ 2 is designed for use after staining with progressive hematoxylins. After tissues have been sufficiently stained with a progressive hematoxylin, slides are removed from the stain and excess hematoxylin is removed by rinsing the sections in water. The sections are then placed into Clarifier™ 2 for 20 seconds to 40 seconds. A 1-minute water rinse should follow as this stops the reaction and rinses excess acid from the tissue section.
