Title: PRINTED FLOW CELL FOR PHOTOMETER
Abstract:
The invention is directed to a flow cell comprising a sample channel (1) having • - openings (2,3) for input and output of a sample • - at least one opening for a light source (4) and a detector for light (5) • - at least two detection zones (6,7,8), where the light emitted by the light source interacts with the sample • - at least one non-detection zone (9,10) characterized in that the sample channel is configured that • - the detection zones are positioned in the path of light of the light source • - the non-detection zones are positioned out of the path of light of the light source and • - detection zones and non-detection zones are positioned in an alternating sequence in the sample channel. • - and wherein the flow cell consists at least in the portions located in path of light from a monolithic transparent material. The flow cell may be used for detecting the concentration of cells in a sample liquid.
