A cell for the measurement of the dielectric properties of liquids, pastes or flowable solids (i.e. solids whose melting temperatures are low enough to allow them to be poured into the cell) comprises a bullet-shaped internal electrode having its cylindrical portion in register with a surrounding coaxial cylindrical external electrode which is extended at each end by electrically conductive annular guard members insulated from the external electrode by means of spacers of electrically insulating material. The internal electrode is mounted coaxially within the external electrode by means of a tapered male-female centering connector whose male and female elements are both connected to earth.

A method and device for forming openings in a gelatinous substance in a Petri dish in which the Petri dish (6) is lifted towards punch tools (19) until the tools have penetrated the gelatinous substance and are on or near the base of the dish. The dish is then moved with a low amplitude motion perpendicular to the penetration direction, i.e. horizontally to loosen a pellet of the gelatinous substance within each punch tool from the base (6a) of the dish, and finally the dish is lowered to withdraw the punch tools (19) from the dish while suction applied to a compartment (4) communicating with the interior of each tool extracts the punched pellet and clears the tool for a subsequent penetration in the same or a different dish (6).
