A microtome is a precision instrument used to cut very thin slices of material, typically biological tissues, for microscopic examination. It allows scientists and researchers to prepare samples for analysis by creating uniform sections that can be easily observed under a microscope. Microtomes are essential in fields like histology and pathology, where they help in studying the structure of cells and tissues. The slices produced can be as thin as a few micrometers, enabling detailed examination of cellular components. This tool is crucial for diagnosing diseases and understanding biological processes.
