<p>Device for liquid flow cytophotometer including a device for hydrodynamic focussing (4, 6) of a cell- or particle-suspension towards a measuring area, and an optical excitation- and detection-system (9), preferentially based on oil immersion optics, characterized by the focussing device being formed as a - in relation to the system"s optical axis - rotating nozzle assembly (1) directed towards a surface (7) which is open in relation to the surrounding atmosphere and situated on the optics (9), forming the optics" measuring area, thus supplying a laminar liquid flow of the above-mentioned suspension. </p> |
