Abstract: The invention refers to a chamber for measurements of electrical properties of reactive powder or liquid samples, allowing the measurement of various electrical parameters to be carried out. The present invention provides the chamber in two variants of embodiment: the multiple use chamber and the single use chamber. The construction of the chamber provides the possibility of carrying out the measurements with the sample placed directly between parallel active surfaces of the electrodes placed coaxially and sliding in a precise manner in to a thin-walled cylinder made of insulating material providing electric insulation. Elements remaining in contact with the sample are made of chemically inert materials. Additionally, a module containing a pair of the electrodes and the cylinder made of insulating material is detachable from the rest of device elements, that enables its loading and hermetic closure in a glovebox filled with inert gas.
