Deterioration of Nitrocellulose Solutions Caused by Light

Abstract

Solutions of Parlodion stored in clear glass bottles, and subjected to the usual lighting of laboratory work tables, deteriorate progressively. Blocks of nervous tissue stained by Cajal's formula No. 6 underwent marked fading when embedded in old, light-affected Parlodion solutions. Storage of nitrocellulose, either as a solid or in solution, should be in darkness, in a dark colored bottle, for example.
