Achieve sharp, resilient nuclear staining with our Weigert's Iron Hematoxylin Kit. A cornerstone of special staining protocols, this two-part iron hematoxylin delivers crisp, well-defined nuclear detail that resists the acidic and differentiating solutions used in trichrome, elastic, and other connective tissue stains. Its alcohol-resistant, acid-fast staining makes it the reliable foundation for Masson's Trichrome, Van Gieson, and Verhoeff-Van Gieson procedures, ensuring nuclei stay distinct through subsequent steps. Supplied as separate solutions for mixing fresh at time of use, the kit is formulated for consistent, reproducible results slide after slide.
