Certified Biomedical Equipment Technician (CBET) 2025 – 400 Free Practice Questions to Pass the Exam

The correct answer, microtome, refers to a specialized instrument designed specifically for cutting very thin slices of tissue, typically ranging from 1 to 10 micrometers in thickness. This is crucial in histology as it allows for the detailed examination of tissues under a microscope, enabling pathologists and researchers to identify cellular structures and analyze tissue pathology accurately. The microtome operates either manually or automatically, using a sharp blade to achieve consistently thin sections that do not distort the tissue integrity.

In contrast, a macrotome is used for larger specimens and typically cuts thicker sections, which may not be suitable for microscopic examination. The sliceacator is not a commonly recognized term in the field of biomedical equipment and does not refer to a standard tissue slicing device. A desiccator, on the other hand, is used for drying and storing samples in a moisture-free environment, which is unrelated to slicing tissues for microscopic analysis. Thus, the microtome is uniquely suited for the task at hand, making it the correct choice.
