Colorimeter including a flow cell having end windows

摘要: A colorimeter including a flow cell having an open-ended tubular body providing longitudinal sight passageway, intermediate light source and detector for colorimetric analysis of liquid sample within the fluid inlet outlet ports, one through sidewall structure adjacent each end body. Light-permeable seals are provided at ends body, least which has inclined inner surface generally opposite ports to minimize stagnant regions in passageway. An optical element is compensate refractive characteristics interface with aforementioned surface, so that passes from substantially axially
