1 Ultracentrifuge in laboratory of DuPont's Chemical Department 1955 E.I. du Pont de Nemours & Company (originator) Ultracentrifuge in laboratory of DuPont's Chemical Department at the company's Experimental Station rotates solutions at such high speeds as to exert a centrifugal force 270,000 times the force of gravity. By use of this instrument, the physical chemist is able to determine the weight of molecules of various materials.

The ultracentrifuge used at the Experimental Station to determine molecular weights of colloidal materials such as proteins, cellulose and rubber. The upper half of the housing is shown at the top of the picture. Observations are made through the 'window' in the center of this section of the housing. The rotor, with cell at center top to hold material being studied, is shown in place for operation. Rock quartz windows in either end admit light projected from the rear and through the windows. One of the special bearings is shown also. The ultracentrifuge when spinning at the rate of 60,000 revolutions a minute exerts a force equal to 250,000 times that of gravity. If gravity pulled as hard as this machine, a pound would weigh 125 tons.

7 Testing motor fuels at DuPont's Petroleum Laboratory 1955 E.I. du Pont de Nemours & Company (originator) In an effort to find out more about motor fuels, lubricant and engine performance, a test car is driven for miles on an instrumented treadmill under simulated road conditions at DuPont's Petroleum Laboratory. The treadmill can be tilted to any desired grade and a wide tunnel in the background simulates the windage on a moving car. In other tests, a fleet of cars and trucks are driven thousands of miles under actual road conditions.

13 Synthetic lilac perfume 1937-09 E.I. du Pont de Nemours & Company (originator), Duryea, Drix (photographer) Large bottles of terpineol, the chief constituent of synthetic lilac perfume. Reflected in the vessels of crystal clear oil are the large drums of the raw materials for perfume manufacture. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery- there was no lilac perfume, for no satisfactory mean has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor...

Large bottles of terpineol, the chief constituent of synthetic lilac perfume. Reflected in the vessels of crystal clear oil are the large drums of the raw materials for perfume manufacture. Until the lilac odor was synthesized-one of the outstanding achievements of the chemical laboratory in perfumery- there was no lilac perfume, for no satisfactory mean has ever been found of extracting this natural oil. Moreover, there is no known natural extract so sweet or so peculiarly powerful in odor as synthetic lilac. Chemistry converts volatile turpentine into fragrant lilac rivaling natural's illusive floral fragrances.

23 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.

Speed that splinters seconds into millionths is essential elements in tools used in chemical research. Here an ordinary egg, exploded by a bullet, is frozen in space by a high speed camera. The electronic camera which caught this dramatic picture is but one of many recently developed laboratory tools at the DuPont Company's Experimental Station which give research workers heretofore unobtainable insight into the deepest secrets of nature. This new knowledge, backed up by experience and modern facilities, is applied to filling human wants and needs.
