- Description
-
Accuracy is extremely important in testing dyestuffs. Delicate balances are used, it being frequently necessary to weigh as little as 1 milligram of color. The DuPont Technical Laboratory is equipped with sensitive scientific balances, handled by trained operators to weigh out quantities of color used in making dyeings of prescribed strength on cotton, wool, rayon, acetate, nylon, silk, paper, leather etc.

The equipment illustrated is typical of what the visitor will see in most research and application laboratories. Known as reflux units, they are used as testing instruments in ascertaining the resistance of a brown dye to various metals. Each flask contains a piece of metal and a prescribed quantity of dye in solution. After continuous boiling for a 24 hour period, the dye is carefully checked and tested, to determine what effect if any the metal may have had upon its shade, strength,...

Known as reflux units, they are used as testing instruments in ascertaining the resistance of a brown dye to various metals. Each flask contains a piece of metal and a prescribed quantity of dye in solution. After continuous boiling for a 24 hour period, the dye is carefully checked and tested, to determine what effect if any the metal may have had upon its shade, strength, physical composition or any other property essential to a satisfactory dying operation. Thus the user has predetermined information grading the characteristics of a color available to him.

- Description
-
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.
