Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refrigeration function predominates over sectioning
Cryostats emphasizing cooling classified in 8418; microtome specificity keeps in 9027 per use rules.
If for cryostat microtome blade assemblies or chucks
Parts suitable solely for these instruments classified separately per Chapter 90 note 2.
If dental lab microtomes for prosthesis preparation
Dental-specific instruments may shift to 9018; general pathology stays in 9027.
