ERIOCHROME CYANINE R AR Reagent for Aluminium

Nuclear staining with Fe-ECR provides tinctorial features similar to regressive aluminum-hemateins as well as resistance to acidic solutions such as those of iron hemateins. Fe-ECR also stained selectively intestinal cells of the diffuse neuroendocrine system (DNES).

In the case of aluminum and its alloys, anodizing using Barker’s reagent (1.8% HBF4 in distilled water) is widely applied to reveal the grain structure. … The reagent was called “Weck’s reagent” which contains 4 g of KMnO4, 1 g of NaOH and 100 mL of distilled water.
