The razor is set before our microtome in a razor-holder which is versatile. The material, inserted in the paraffin square, is settled on the square holder which can be settled to a customizable attachment. There is a scale showing the thickness of the segment in microns. The thickness is balanced by moving a screw. In addition, the square holding attachment can be advanced or in reverse by turning a handle put at the back of the microtome. These days, our microtomes are regularly utilized. A Shaking microtome has a similar working guideline.
