Laboratory instrument (1, 1', 1", 400, 500) for the instrument-controlled treatment of a partial problem in a treatment process for handling at least one laboratory sample, which treatment process relates to the handling of a problem comprising partial problems when handling the at least one laboratory sample using the laboratory instrument and at least one further laboratory instrument (1, 1', 1", 400, 500), the laboratory instrument being selected of the group of laboratory instruments including a laboratory centrifuge, a thermocycler, a laboratory spectral photometer, a cell counting instrument, a laboratory incubator, a laboratory shaker, a laboratory mixer, a laboratory freezer, a bioreactor, a safety work bench, a sample plate reader, and a pipetting machine, the laboratory instrument comprising: - a treatment apparatus for the instrument-controlled handling of the partial problem, - a control apparatus for controlling the laboratory instrument, - a user interface apparatus (5; 404; 504) for the manual entry of data by a user and for displaying information, - at least one interface apparatus for establishing at least one data connection to the at least one further laboratory instrument (1, 1', 1", 400, 500); each of the laboratory instrument and the further laboratory instrument being configured to work independently as a stand-alone instrument, which requires a user input from the user interface apparatus and does not require a data connection with a further device in order to work in a conventional operating mode, which provides the treatment of the at least one laboratory sample using its treatment apparatus; wherein the control apparatus is programmed: • to receive first treatment data, which can be used for handling the partial problem, via the at least one interface apparatus and • to perform the control of the handling of the partial problem using these first treatment data, • to provide, in particular generate, second treatment data as a function of the handling of the partial problem, which second treatment data can be used by the further laboratory instrument (1, 1', 1", 400, 500) for handling a further partial problem of the treatment process, • to bundle first and second treatment data and • to output at least these bundled first and second treatment data as further treatment data for use by the further laboratory instrument via the at least one interface apparatus. the laboratory instrument comprising: - a treatment apparatus for the instrument-controlled handling of the partial problem, - a control apparatus for controlling the laboratory instrument, - a user interface apparatus (5; 404; 504) for the manual entry of data by a user and for displaying information, - at least one interface apparatus for establishing at least one data connection to the at least one further laboratory instrument (1, 1', 1", 400, 500);
