The invention relates to a method for closed sampling from filling plants comprising the following steps in:



filling a sample quantity into a container (1) with a wall (3);
applying a reinforcing element (20) to the container (1) with the wall;
introducing a fracture point (22) into the wall of the container (1) in the area of the reinforcing element (20);
introducing a sampling attachment (30) with hollow tube (40) into the wall of the container (1) in the area of the fracture point (22);
filling a sample container (50) connected to the hollow tube (40) once or several times;
removing the sample container (50) from the hollow tube (40) and closing the sample container (50);
removing the sampling attachment (30) with hollow tube (40) from the container; and
sealing the fracture point (22) of the container in the area of the reinforcing element (20).




The subject matter of the invention is also a sampling device, in particular for carrying out the method.
