Abstract : An adaptor for supporting small thin film or fibrous samples of material between the electrodes of a resistivity cell is described which comprises a pair of stacked electrically insulating plates. Each plate has a central electrode therethrough and presents confronting conductive samples of known surface area for sandwiching the sample therebetween for resistivity measurement, and a guarding electrode on one confronting plate surface and surrounding the central electrode thereon for electrically contacting the guarding electrode of the resistivity cell. The plates may be hingedly joined along respective sides and include fittings to maintain the confronting electrode surfaces in concentric alignment with the sample therebetween.
