The invention relates to a device for carrying out the scientific studies. The object of the invention is to provide a new technical solution, the scientists for tests can be used in order to produce different solid and / or liquid and / or gaseous substances under aspects of their production from known or new raw materials, their release from existing mixtures or their use for new applications, to be tested. This object is achieved in that the device in the form of a spherical pressure vessel (1), which on its lower spherical shell surface in the functional position, an opening (2), along the perimeter line of this opening (2) a reaction tube (3) is arranged, the pipe jacket can be acted upon as electrical cathode and which is in its interior a spirally configured assembly (4), which can be acted upon as electrical anode and that, starting from the opening (2) along the central longitudinal axis (m) of the reaction tube (3) according to the bottom up to an upwardly open inlet region of a funnel (5) extends, in the direction of the central longitudinal axis (m) of the reaction tube (3) is displaceable, and with its downwardly open hopper outlet with a lower opening (6) of the reaction tube (3) is in operative connection with a two-way valve (7) can be adjusted.
