The invention relates to a sampling device for toxic and/or radioactive substances, in which rotational and oscillating movements are to be performed and a needle-head charging system is provided for at least one sample vessel which, by means of the rotational and oscillating movements exerted onto a rotating cylinder, can be moved to the needle-head charging system and to an inlet and outlet for the sample vessel, the rotating and oscillating movements being transmitted by means of a drive shaft, the needle-head charging system and the inlet and outlet being arranged above the rotating cylinder and a skimmer being provided, which is used to remove the sample vessel, after it has been charged, from the needle-head charging system and hold it within the rotating cylinder (according to Patent Application P 3342470.5).
<??>Said sampling device is now to be improved with regard to the needle-head function, the radiation protection conditions and the maintenance of the parts conducting the sample medium.
<??>The solution is characterised in that
a) in the interior of a housing, which accommodates the needle-head charging system, the rotating cylinder, the skimmer and the inlet and outlet, a needle-head accommodating disc having at least one accommodating bore for a needle head is disposed centrally in such a way that the needle head can be replaced through the cover of the housing, and in that
b) bores are provided in the needle-head accommodating disc, by means of which bores a connection between the needles of the inserted needle head ...
