<p>Apparatus to analyze a biological sample (11) contained in a container (12), comprising an examining device (16) able to perform an optical measurement on the biological sample, based on light-scattering technology, at least of the bacterial growth in the biological sample. The examining device is provided with emitter means (20) able to emit a first light beam (BO) toward the container (12) of the biological sample and sensor means (22, 24) able to detect at least a light beam diffused from the container (12) of the biological sample and to transmit a relative signal, correlated to the light beam diffused, to a control unit (18) which is able to process, directly or indirectly, the signal in order to verify at least the possible bacterial growth in the biological sample (11). The container (12) is disposed along a determinate lying plane (P) and comprises at least a containing micro-element (14) able to contain at least a part of the biological sample and inside which a liquid culture ground is provided so as to allow bacterial growth in the biological sample. The emitter means (20) and sensor means (22, 24) are able to be located on each occasion in correspondence with the containing micro-element (14). The sensor means (22, 24) comprise first sensor means (22) disposed on the same side of the emitter means (20) with respect to the lying plane (P), and second sensor means (24) disposed on the opposite side of the emitter means (20) with respect to the lying plane (P). The first sensor means (22) are able to detect a back-scattering radiation coming from the determinate containing micro-element (14). The second sensor means (24) are able to detect a forward-scattering radiation coming from the determinate containing micro-element (14), from which back-scattering radiation (B2) and forward-scattering radiation (B4) derive respective first and second signals transmitted to the control unit.</p> |
