1. A cuvette for the determination of a chemical component of a fluid by photometric evaluation through the fluid, comprising:

  • two, non-adsorbent, planar-shaped parts at least one of which is transparent in the spectral range used for the evaluation, the planar-shaped parts being joined together at less than all their perimeters; and

    a similarly-transparent, substantially-planar distance piece comprising a filamentary reticulation between the two planar-shaped parts for receiving the fluid and spacing the planar-shaped parts in parallel to one another by the thickness of the distance piece across a sufficient number of filaments to thereby determine a definite path length of light through the cuvette for the evaluation.
