    • The invention relates to the extraction of a frozen hydrated sample for TEM (Transmission Electron Microscope) inspection, such as a vitrified biological sample, from a substrate and the attaching of said sample to a manipulator. Such a hydrated sample should be held at a cryogenic temperature to avoid ice formation. By melting or sublimating a part of the sample material outside the area to be studied in the TEM and freezing the material to the manipulator (10), a bond is formed between sample (1) and manipulator. This makes it possible to transport the sample from the substrate to e.g. a TEM grid.In a preferred embodiment a part (2) of the manipulator (10) is held at a cryogenic temperature, and the melting or sublimation is caused by heating the tip (3) of the manipulator by electric heating of the tip and then cooling the tip of the manipulator to a cryogenic temperature, thereby freezing the sample (1) to the manipulator.
    • 本发明涉及从基材提取用于TEM(透射电子显微镜)检查的冷冻水合样品,例如玻璃化生物样品,并将所述样品附着到机械手。 这样的水合样品应保持在低温温度以避免冰层形成。 通过在TEM中将待研究区域外的一部分样品材料熔化或升华,并将材料冷冻至机械手(10),在样品(1)和机械手之间形成结合体。 这使得可以将样品从衬底输送到例如。 一个TEM网格。 在优选实施例中,操纵器(10)的部分(2)保持在低温温度,并且通过对尖端的电加热来加热操纵器的尖端(3),然后冷却尖端而引起熔化或升华 的操纵器到低温,从而将样品(1)冷冻到机械手。
