Abstract: A portable vacuum antioxidant bag installed in an electron microscope to prevent oxidation of a sample includes a magnet fixing part formed by attaching a flexible magnet to an opening of the portable vacuum antioxidant bag, a gas inlet and a gas outlet formed on two sides of the portable vacuum antioxidant bag, the gas inlet through which gas is injected into the portable vacuum antioxidant bag, and the gas outlet through which air exits the portable vacuum antioxidant bag by the injected gas, and a pair of gloves formed in a shape of hands toward an inside of the portable vacuum antioxidant bag, wherein the portable vacuum antioxidant bag is tightly contact with the electron microscope due to the magnetic force by the magnet fixing part.
