Chinese scale for grading pharmaceutical solutions, divided into five colour series: Yellowish green (YG1 - YG10); Yellow (Y1 - Y10); Orange Yellow (OY1 - OY10); Orange Red (OR1 - OR10); Brownish Red (BR1 - BR10).

The Chinese Pharmacopoeia is similar in principle to the European Pharmacopoeia (EP) Colour in that the colours are made using yellow red and blue primary solutions.

However the yellow solution is different to the EP and the proportion of solution used and the colour designations are different.

This scale is available as an upgrade to our PFX and PFXi instruments.
