9027.90.20.00 - Microtomes 🖩

This classification pertains to microtomes, which are specialized instruments designed for slicing extremely thin sections of biological tissues or other materials. These sections are crucial for microscopic examination in fields such as histology, pathology, and materials science. The primary function of a microtome is to produce uniform, thin specimens that can be stained and observed under a microscope to identify cellular structures, diagnose diseases, or analyze material properties.

Within the broader category of "Instruments and apparatus for physical or chemical analysis...; microtomes; parts and accessories thereof," this specific node focuses exclusively on the microtome instrument itself. It is distinct from the sibling category, ": Parts and accessories:", which covers components used to repair or assemble microtomes rather than the complete functional unit. Therefore, items classified here must be fully assembled and operational microtomes.

As this is a leaf node in the HTS structure, there are no further subdivisions. Classification within this code is therefore definitive for complete microtome instruments. When classifying, attention should be paid to the primary function of the instrument, which is the precise cutting of thin sections for microscopic analysis. Any modification or accessory that forms an integral part of the microtome's operation and is not a separate replacement part would fall under this classification.
