A machinery for the preparation and the analysis of one or more slides according to an immunofluorescence technique and comprising: - A loading station (15, 16, 17) suitable for the arrangement of one or more containers for the containment of test liquids and/or samples of product; - A positioning station of one or more slides comprising a support base provided with a plurality of seats that are each one in the form of a containment frame suitable for holding one slide, so that the slide is raised over the surface of the support base; - A containment station of one or more slide-covers; - An analysis station comprising a microscope for the digital acquisition of the images at one or more magnifications; - Characterized in that the positioning station is removable from the machine and the following are further comprised: - One or more covers of such a size as to be applied to cover each slide arranged in the seat, the cover having a top surface provided with a gripping handle and lateral walls that depart orthogonally from said top surface towards the opposite part of the handle, said cover being substantially rectangular-shaped and with a size so that it can be applied to entirely contains inside its volume, delimited by the top surface and the said lateral walls, the containment frame forming said seat and the slide placed on the seat; - wherein the seat is further conformed to allow the arrangement of silica gel and the arrangement of the slide in said seat on the silica gel, in such a way that the combined effect of the cover with said silica gel reduces the deterioration time of the substrate of the slide; - A container for the containment of one or more of said covers, said container being removable; - And wherein an assembly mobile inside the area defined by said machinery is further comprised and controlled to operate the removal of the cover/s applied each one on a slide positioned in a seat once the phase of pre-dilution of the samples has been completed, and arranging said covers inside the container; - The assembly being further controlled in such a way as to move through said stations (15, 16, 17; 19; 22; 23) so as to prepare one or more slides in accordance with a pre-defined protocol leaving the slides on the support base, wherein said assembly is controlled for being positioned in correspondence of the loading station (15, 16, 17) to take liquids and/or samples of product to then arrange them on the slide/s in correspondence of the positioning station and further controlled for being positioned in correspondence of the station to collect the slide-cover/s and arrange it/them on the slide/s, and, at the end of said preparation of the slides, moving said slide/s in the corresponding analysis station for a subsequent acquisition of one or more digital images. - A loading station (15, 16, 17) suitable for the arrangement of one or more containers for the containment of test liquids and/or samples of product;
