An apparatus for treating samples of biological, microbiological and/or chemical material, comprising at least: a support device for samples of biological, microbiological and/or chemical material, the support device comprising: a transportable support body provided with a plurality of housing seats suitable for each receiving at least a sample of biological, microbiological and/or chemical material, and an electronic memorising device; an interface device for interfacing with the support device, wherein said interface device comprises at least a support portion suitable for housing said support device; a processor; at least a software program memorised on said processor; at least a visual signalling device, operatively connected to said processor and controlled by said software program and suitable for emitting a light signal on said support body of said support device housed on said interface device; wherein the software program is configured to: determining a work pattern with the positioning of the samples on the support body; commanding the visual signalling device for progressively indicating through the light signal the positions or housing seats, depositing seats or inoculation seats of said samples on said support body; memorising on the electronic memorising device a plurality of data relating at least to said samples of material and to the specific position of each of said samples of material on said support body, in correspondence of each of said housing seats; characterized in that the electronic memorising device is constrained to said support body for being transportable together with said support body; and in that the apparatus further comprises at least a registration device of images or photographs for recording images at least of said support body during the positioning of a plurality of samples of material and wherein the registration device is connected to said processor in such a way as to transfer said images to said processor, which is configured to conserve and/or verify said images to confirm a real arrangement of said plurality of samples of material on said support body. a support device for samples of biological, microbiological and/or chemical material, the support device comprising: a transportable support body provided with a plurality of housing seats suitable for each receiving at least a sample of biological, microbiological and/or chemical material, and an electronic memorising device;
