8543.70.97.00 - Plasma cleaner machines that remove organic contaminants from electron microscopy specimens and specimen holders

This HTS subheading, 8543.70.97.00, specifically covers plasma cleaner machines designed for the meticulous removal of organic contaminants from electron microscopy specimens and their corresponding holders. These specialized machines utilize plasma technology to achieve a high degree of surface cleanliness, which is crucial for obtaining accurate and high-resolution images in electron microscopy.

This classification is distinct from its sibling categories, such as those for electrical nerve stimulators (8543.70.85.00) or devices with translation and dictionary functions (8543.70.88.00), by its singular focus on surface cleaning for scientific imaging applications. Unlike broader categories of "other" machines, the defining characteristic here is the specific application of plasma for contaminant removal in a laboratory or research setting.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under 8543.70.97.00 is therefore definitive for plasma cleaning apparatus meeting the specified functional criteria. The key classification criteria revolve around the machine's inherent function as a plasma generator intended for surface decontamination of scientific specimens and related equipment used in high-magnification microscopy.
