Merck, S4892-3EA, Wheaton staining dishes

Microscopy is a method of viewing objects that lie outside the resolution of the human eye and can be examined. The objects to be observed are magnified to such an extent that they can be displayed as images. For sample preparation, the objects to be examined are cut into very thin slices. These sections are then applied to an object slide and covered with a cover glass and appropriate solutions. To view the sections under the microscope, the sections on the slide must be filled in a staining trough and stained with an appropriate staining solution.
