Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.
