Cuvette for the photo determination of chemical components in fluids
First Claim
Patent Images
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.

Abstract
A cuvette for the determination of a chemical component of a fluid by photo evaluation has two planar-shaped parts parallel to one another at least one of which is transparent in the spectral range used for the evaluation. A planar distance piece of a filamentary reticulation for receiving the fluid therein spaces the planar-shaped parts apart to set the length of the light path through the cuvette for the photo evaluation.
