The Grids are usually somewhat thicker than similar TEM grids made by electro plating processes which makes them stiffer and easier to handle without the danger of bending, but still maintain a good definition of the grid bars. The wide rims (350-400μm) on the Grids provide additional stiffness and minimize the potential of interfering with the sample when picking up and handling the grids with tweezers. The grids have a shiny (smooth) finish on one side and matte (rough) or dull finish on the other side. Grids have all been inspected before packaging.
