1 Studying chemical safety at the Haskell Lab for Toxicology and Industrial Medicine 1955 E.I. du Pont de Nemours & Company (originator) Growing importance of chemistry in modern life carries the challenge of safeguarding public health and safety against unforeseen hazards. New chemicals are subjected to elaborate and exhaustive tests before they are permitted to become commercial items. In DuPont Haskell Lab for Toxicology and Industrial Medicine, an experienced staff carried out the work started more than 20 years again. Here a biochemist makes blood cell study at the $2,000,000 lab near Newark, Delaware.

4 High vacuum apparatus 1955 E.I. du Pont de Nemours & Company (originator), Rittase, William R. (photographer) This complicated piece of high vacuum apparatus in the laboratories of the Chemical Department of DuPont is used for measuring the surface are of fine powders, such as pigments. The process involves measuring the amount of gas such as nitrogen absorbed on the surface of a given weight of the powder. The greater the amount of gas absorbed, the greater is the 'specific surface area'. In the case of certain extremely fine powders, the total surface area of the particles in one teaspoonful may...

Dr. Paul W. Morgan of DuPont's Textile Fibers Pioneering Research Laboratory demonstrates the making of nylon, instantaneously, at room temperature, without any apparatus other than a drinking glass, a small jar or beaker. Practical commercial manufacture of nylon requires high temperatures, precision controls and complex and expensive equipment. Dr. Morgan shows here how a nylon rope can be drawn from a beaker when a solution of a fast reacting diacid chloride in a water immiscible solvent is brought into contact with an aqueous solution of an aliphatic diamine. A film of high polymer forms where the two solutions meet which is called the interface. The film can then be pulled from the interface immediately and as if by magic, it is continuously replaced to form a long endless cord of polyamide-hence the nylon rope trick. This particular method of making nylon is an invaluable laboratory tool to researchers and teachers in chemistry because permits polymeric experimentation which are both inexpensive and uncomplicated.

7 Preparing a monomer for polymerization study 1955 E.I. du Pont de Nemours & Company (originator) In a fundamental research project, a scientist in the Central Research Department at the DuPont Company's Experimental Station, prepares a monomer that will later be used in a polymerization study. One of the components boils at 29 degrees below zero and must be cooled to keep it in liquid form. This causes the frost or ice formation on the tubes in the picture. The coolant is a mixture of dry ice and acetone.
