Cuvette constructions

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light > Arrangements or apparatus for facilitating the optical investigation > Cuvette constructions

CPC:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light (G01N3/00 - G01N19/00 take precedence) > Arrangements or apparatus for facilitating the optical investigation > Cuvette constructions

CPC subdivides this area 6x more granularly than IPC with 16 additional codes.

16 codes are CPC-only extensions.

Note: 12 CPC extensions are marked as secondary classification only.

2 shared codes have differing titles between IPC and CPC.
