  • Cuvette and cuvette-transporting apparatus
    Patent number: 5658532
    Abstract: A cuvette, to be used for measuring the properties of liquid contained therein by applying a measuring beam of light from a direction intersecting the vertical axis of the cuvette, includes a rectangular or square-outlined portion on the top thereof as viewed in a horizontal cross section, a cylindrical portion below the top portion, and a lower rectangular or square portion provided vertically below the cylindrical portion and having four sides parallel to these of the top rectangular portion, respectively. Thus, the cuvette does not unfavorably rotate when measuring the absorption of light transmitted therethrough. Further, an apparatus for transporting the aforementioned transparent cuvette, accurately controls the position of the cuvette during transportation so that a flat surface thereof can be irradiated with a measuring beam of light.
