Microtome recommended for electron microscopy
WebA microtome is used to make thin slices of tissue (usually 4 μm but can be 2–10 μm). The cut tissue is floated over a water bath, in order to eliminate wrinkles and distortion in the tissue, and picked up on a slide. The temperature of the water bath depends on the type of wax and is typically 5–9 °C below the melting point for the wax.

WebUltramicrotomes are sophisticated devices used to cut ultrathin sections for light and electron microscopy. To produce such thin sections, an ultramicrotome uses a very sharp blade made of glass, diamond or sapphire. 5. Laser Microtome Blade You won't need a traditional knife with a laser microtome. WebThis chapter describes the practical details involved in the successful sectioning of plastic-embedded specimens for electron microscopy. The focus will be on those parts of the process that are really key to the successful sectioning of any biological material, i.e., the proper shape and size of the specimen, sharp knives and how to make them, and the …
