A Rotary microtome cuts the sections of biological specimens into thin slices for use in microscopy. It gets its name because of the rotary action of the handwheel used for slicing samples. It is used to prepare thin layers of bone, mineral, teeth, and hair with section thicknesses ranging from 1-micron to 60 microns. For hard materials that use synthetic resins, they can slice up to 0.5 microns.
