Colour Standard

Carl ROTH offers an extensive range of calibration and control standards. These products are manufactured from highly pure starting material and are specially tested for each application. The corresponding batch-specific certificate of analysis is available online. Each product series offers excellent value for money.

The light yellow Gardner colour numbers 1-8 are based on potassium chloroplatinate solutions, the colour numbers 9-18 on iron(III) chloride, cobalt(II) chloride and hydrochloric acid solutions. They can be used to determine the colour number of similarly coloured liquids, such as vegetable oils or mineral oils.
Our colour standards according to Gardner are prepared from high-quality reagents by weighing (weight %). The standards are checked by means of a spectrophotometer. The batch specific Certificates of Analysis are available online.
