A microtome is a precision instrument used in histology to cut extremely thin, uniform sections of tissue for microscopic examination. These sections, typically ranging from 0.5 to 100 micrometers in thickness, are essential for detailed analysis of cellular and tissue morphology. Depending on the specimen and desired thickness, microtomes utilize steel, glass, or diamond blades. Common types include rotary microtomes, widely used for paraffin-embedded tissues, and sliding microtomes. The instrument ensures consistent sectioning, which is vital for diagnostic pathology, research, and teaching applications, allowing for high-quality slide preparation.
