Typical applications for this design of microtome are of the preparation of large samples, such as those embedded in paraffin for biological preparations.
For larger pieces of tissue, thin sections ( slices ) are made using a microtome; these slices can then be mounted and inspected.
Alternately this design of microtome can also be used for very hard materials, such as bones or teeth, as well as some ceramics.
