Abstract: A flow cell having a nonmetallic elongated open-ended tubular body providing a longitudinal sight passageway in a portion of the light path between a light source and a light detector for colorimetric or densitometric analysis of a liquid sample within the passageway, the body having fluid inlet and outlet ports, one through the side-wall structure of the body adjacent each end of the latter. Light-transmitting fluid seals are provided closing the respective ends of the body, at least one of which seals has an interface with the liquid sample in the sight passageway and is structured of a material having a higher refractive index than the tubular body, so as to provide a light pipe for increasing the transmission of light through the flow cell sight passageway to the light detector.
