Abstract

The apparatus provides a direct reading of the volume of a microscopic particle, such as a biological cell. The cells, or other particles whose volumes are to be measured, are suspended in a dark fluid to which the cells are inert. The cells are transparent to the wavelength of light used in the apparatus while the dark fluid is substantially opaque to it. When the cells are passed single file through a capillary tube between the light source and a photocell, the quantity of light passed by each successive cell is an approximate measure of the volume of each cell.
