Ultramicrotomes

Part of speech: noun

Definitions

1. A type of precision instrument used in microscopy to cut extremely thin sections of material for examination under a microscope; an essential tool in both biological and materials science for sample preparation; designed to produce slices at the nanometer scale, enabling detailed imaging of cellular structures and materials
2. These specialized devices are used for creating ultra-thin sections, often less than 100 nanometers, that allow researchers to study samples at an incredibly fine resolution; crucial in fields such as pathology and materials research; they provide essential insights into the ultrastructure of cells and materials
3. An ultramodern tool for sectioning specimens into minuscule slices, supporting advanced microscopy techniques in various scientific fields; used to prepare samples with high precision for thorough investigation; they play a vital role in revealing intricate details of structures that are not visible in thicker sections

Etymology: "Ultramicrotomes" is the plural of "ultramicrotome," a compound of the prefix "ultra-," meaning beyond or extremely, and "microtome," a device for cutting very thin slices of material for microscopy. The plural simply applies to several such instruments. Because the word is a plain combination of two existing parts, its meaning follows directly from them: a microtome cuts specimens into sections thin enough to see through, and the "ultra-" version pushes that thinness much further, into the range of nanometers.
