    Abstract: A handling device for thin sections, in particular cryosections, which serves as a multifunctional device for transferring, pressing, and holding the thin sections. The device possesses a holder for at least one carrier grid, this holder comprising a base plate and a positively-guided cover plate which can be moved onto the base plate. In addition, means are provided for the purpose of clamping the cover plate against the base plate and hence against a thin section which is present on the carrier grid. A separate holder plate is preferably detachably located in the base plate, the carrier grid being permanently attached to this holder plate, which is matched, in shape and dimensions, to the specimen holder of an electron microscope.
