Abstract: An optical flow cytometer for blood cell characterization, comprising: a flowcell providing a blood cells flow, at least one light-emitting diode for illuminating blood cells that are flowing in the flowcell, an epifluorescence module in which a same first lens group is used for focusing the—excitation light in the blood cells flow and for collecting fluorescence light coming from each blood cell, and a unitary photodetector for detecting the epifluorescence light coming from the first lens group, at least one of the following measurement modules includes: a light scattering measurement module, an axial light losses measurement module, a particle impedance measurement module.
Abstract: A fluid connection device is provided for biological analysis apparatuses, intended to simultaneously connect a plurality of fluid conduits and at least one fluidic component including a connecting surface with a plurality of fluid ports, the device having: (i) a holding plate, (ii) removable attachment structure capable of pressing the holding plate against the connecting surface, (iii) connectors suitable for being fixed to the ends of the fluid conduits and provided with a seal suitable for allowing a sealed connection to be made between the connectors and the fluid ports, holding plate including through-openings opposite the fluid ports and being shaped in such a way as to be able to receive the connectors in through-openings and to hold them pressed against the connecting surface. A biological analysis apparatus implementing the device is also provided.
