Title: High vacuum apparatus
Date(s): 1955
Contributor(s): E.I. du Pont de Nemours & Company (originator), Rittase, William R. (photographer)
Description: 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...
