Laboratory wastes containing glutaraldehyde, paraformaldehyde, osmic acid and cacodylic acid were mixed with tannic acid and then with gluten. The osmium/tannin/gluten/aldehyde complex thus precipitated was separated as a cake by paper filtration. The filtrate containing cacodylic acid was supplemented with starch and warmed. This embedded filtrate in starch paste was air-dried together with the filter cake, and stored in a desiccator. The method also appears useful for storage of similar laboratory wastes.
