This image for day 116 of #LMB365 is a dish of negatively stained grids, discarded after use in the general-use Spirit, which is a 120 kV transmission electron microscope (TEM). Samples are applied to the grid, then surrounded by heavy metal stain that blocks the electrons, thereby enhancing contrast.
