title: A simple device for staining electron microscopy grids.
abstract: A simple holder for electron microscopy grids is described. It consists of a rod covered with dental wax (Ladd, Cat. No. 32165). Multiple slits for holding grids are made in the wax. The rod is attached to a rubber cork that fits into the test tubes filled with staining or rinsing solutions. The device has simplified and standardized the staining procedure, and stain precipitates due to air exposure are avoided.
