About heading 9027

Instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes; parts and accessories thereof

Heading 9027 covers laboratory and field instruments used for physical or chemical analysis, such as gas analyzers, chromatographs, spectrometers and exposure meters, plus microtomes and their parts. The heading is split first by instrument family: gas or smoke analysis apparatus, chromatographs and electrophoresis instruments, spectrometers using optical radiations, other optical-radiation instruments, and a residual group for mass spectrometers, NMR instruments and other analyzers. A final group covers microtomes and parts and accessories, with separate lines for electrical and non-electrical goods and for printed circuit assemblies.
