ABSTRACT:
A chemical analysis slide frame assembly including first and second slide frames each having an opening whose area is smaller than the area of a chemical analysis film inserted therein and a third slide frame disposed between the first and second slide frames. The third slide frame has an opening which is adapted to receive the chemical analysis film and is shaped so as to substantially prevent the displacement of the chemical analysis film. The third slide frame has a thickness which is equal to or larger than the thickness of the chemical analysis film. The side wall of the opening in the first slide frame has a small optical reflection factor, preferably is dark so as to provide a small optical reflection factor.
