KNOWLEDGE MATRIX on Instagram: "A microtome is one of the coolest precision tools in medical and biological science, and this video shows exactly how it slices tissue samples into impossibly thin layers—sometimes just 1–5 micrometers thick. The process starts with the tissue being embedded in a solid block, usually paraffin wax, to give it stability. Once the block is secured, the microtome’s ultra-sharp steel or diamond blade moves with extreme accuracy, shaving off thin sections as smooth as a
