New Drug - The final extraction stage in the production of Streptomycin. Bottles containing the Streptomycin-loaded liquid in its penultimate state are spun at 1000 revolutions per minute in a temperature of minus 50 degrees Centigrade, preparatory to "freeze drying".An attempt to find a cure for tuberculosis is being made with the discovery of a new substance Streptomycin found after experiments with penicillin. The new drug, which is a white powder, was first discovered in America, and now a British firm has installed a plant for large-scale production. October 01, 1946. (Photo by Reuterphoto).
