ABSTRACT:
A flow cell for location intermediate a light source and a photosensitive device for light measurement of a fluid therein in a light path. The flow cell has an elongated tubular body member, a debubbler unit, and a tubular fluid outlet tower. The body member has an open-ended bore therethrough constituting a sight passageway. A pair of light transmitting quartz rods are positioned in the respective open ends of the bore to close them. One end of the debubbler unit functions as a fluid inlet conduit and a tubular neck portion extends from the bottom of the debubbler unit and is transversely connected to the open-ended bore of the body member intermediate its ends. A tubular fluid outlet tower has its bottom end transversely connected to the open-ended bore of the body member intermediate its ends. The bottom ends of the debubbler unit and the fluid outlet tower connect to the bore of the body member adjacent the respective internal ends of the light transmitting rods to define the path for fluid flowing through the sight passageway. The internal end surface of the light transmitting rods are flat in the central portion and form a curved surface adjacent their perimeter with the interior surface of the bore of the body member.
