Catalog type History
Provenance Used in Dr. Lin Tsai’s chemical laboratory in support of the Stadtmans. From "Modern Laboratory Appliances, Catalog 59," Fisher Scientific, 1958, page 442: "These flasks are made of regular Pyrex brand glass, coated with ‘Lifetime Red.’ This red coating is effective in filtering ultraviolet light, making these flasks valuable in vitamin work. Each flask has been accurately calibrated within the capacity tolerances prescribed by the National Bureau of Standards."

Dr. Lin Tsai (1922-2003) was born in Hong Kong, coming to the United States for his Master’s and Ph.D. in Organic Chemistry. He became a naturalized citizen in 1962. He came to the National Heart, Lung, and Blood Institute in 1959, where he worked in the Laboratory of Biochemistry with Earl and Thressa Stadtman. His research focus was the stereochemical course of enzymatic reactions and the structures and syntheses of organic compounds. His most important work centered on nicotinic acid metabolism and riboflavin degradation.
