A simple method for handling electron microscope grids is described here. While assuring their identification and safety, this method provides improved handling, temporary storage, and identification of grids bearing ultra-thin sections, and in addition, provides a novel method for preparing bulk samples. Grids are attached at their edges to the weakly adhesive surface of a“Post-it”note pad which sits in a petri dish. The grids are safely immobilized on the pad, classified based on their location, and identified by convenient pad notation. Grid manipulation and identification are simplified using this device, which is easily assembled from readily available and inexpensive materials.
