ANALYTICAL CHEMISTRY
Volk Radiochemical Co. has moved into its new laboratories at 8260 Elmwood Ave., Skokie, III. Volk was organized in 1955 to process radioactive isotopes for clinical and research use. Shown in the photo is the "cold" preparation laboratory where research and development work involving non-radioactive preparations is carried out.
