Abstract
In a method of producing flexible and durable biological specimens, tissue water and any preservative which may be present is replaced by one or more water-soluble impregnating agents by direct molecular substitution without any intermedium or solvent and without removing the tissue lipides. Polyethylene glycol may be used as the impregnating agent. The replacement preferably occurs under vacuum and the specimen may be subsequently sealed.
