Apparatuses and methods of optically analyzing fluid within a pipette are described herein. In an embodiment, an optical reader subassembly includes a pipette configured to aspirate and hold a fluid sample within its tip, a housing configured to receive at least the tip of the pipette through a reentrant seal so that the tip of the pipette is located in a light tight manner within an internal area, a light source positioned to be in proximity to the tip of the pipette when the tip of the pipette is received by the housing, the light source configured to project light through the tip of the pipette and onto the fluid sample held within the tip, and an optical sensor configured to take a reading of the fluid sample held within the tip of the pipette without any of the fluid sample being injected from the pipette.

The method of analyzing one or more samples arranged in sample receptacles of a platform that is configured to receive a plurality of separate samples includes the steps of measuring electromagnetic radiation transmitted or emitted by each sample, repeating the measurement a plurality of times at predetermined intervals, on the basis of each measurement, forming a result matrix comprising a plurality of cells, each cell of the result matrix corresponding to a sample receptacle of the plat-form, wherein a measurement value of each sample is used as an input for determining the visual properties of the respective cell in the result matrix, and displaying the results as consecutive matrixes in respect of time.

A device for screening of a biological sample in a container includes a lighting system having a radiation source, an analysis station having an optical detector and controller. The lighting system includes a filter holder device for selecting two radiations with different wavelengths. The analysis station includes a system for optical detection of the container before analysis of the sample, which includes a backlight panel and an illuminator for illuminating the container and to allow the optical detector to acquire an image of the container and send to the controller information based on the image. The controller controls a rotation system, set up in the analysis station, to position the container so that, in the analysis phase of the sample, the radiation irradiates the sample at an inspection window and a label is arranged on an opposite side with respect to that from which the radiation originates.
