Description
Colour Standard Pt/Co ROTI®Calipure 400 Hazen is a platinum-cobalt colour standard solution for establishing and checking measurements on the Hazen (APHA/Pt-Co) colour scale. Packed as 100 ml in plastic, it serves laboratories engaged in water analysis, process monitoring and chemical quality control. The solution has a density of 1,003 g/cm³ and a boiling point of 100 °C, and carries UN number 3264. This ROTI®Calipure preparation from manufacturer Carl ROTH provides a defined 400 Hazen colour level for visual comparator work and instrumental colourimetry on liquids of intermediate colour intensity. It supports calibration of photometers, verification of analytical methods and routine QC where reproducible Pt/Co reference points are needed. The compact plastic container allows convenient handling and storage, making the standard practical for repeated use in daily laboratory colour assessment workflows.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard Pt/Co, ROTI®Calipure 400 Hazen, 100 ml, plastic
What is this article?
Colour Standard Pt/Co, ROTI®Calipure 400 Hazen, 100 ml, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Spectroscopy & physical property standards, inside Analytical standards & reference materials, in Lab chemicals.
These standards check a physical or optical measurement: a refractive-index liquid, a wavelength standard, a viscosity oil, a melting-point substance. The stated value and its uncertainty are the product. They are not general reagents.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
