These prepared microscope slides are the product of years of experience with preparation techniques and are made in laboratories under scientific control. Microtome sections are cut by highly skilled staff- cutting technique and thickness of the sections are adjusted to the objects. Staining techniques have been selected to ensure a clear and distinct differentiation of important structures with the best permanency of the staining.
