Device for automatic sampling of samples for sample preparation or sample introduction for an analytical apparatus, in particular a chromatograph, with a movable holding arm for exchangeably holding at least one sampler, and with sample containers, from each of which a sample can be taken by means of a sampler that can be moved up and down, wherein, for taking up a sample of granular material, the sampler comprises a cannula as a filling space, in which a cannula plunger is displaceably arranged for opening and emptying the filling space of the cannula that is to be filled with a sample, and the cannula comprises a free lower end which, in order to introduce granular material into the filling space of the cannula, is repeatedly pushed against the bottom of the respective sample container, containing a quantity of granular material, using a predetermined pressure, which can be set by means of a pressure limiter associated with the sampler or with the sample container.
