Description
Colour Standard Pt/Co ROTI®Calipure 40 Hazen is a ready-to-use platinum-cobalt reference solution for colour assessment on the Hazen (APHA/Pt-Co) scale. It supports visual comparison and instrumental colour measurement in water, clear liquids and process samples where a defined 40 Hazen value is required. The preparation shows a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with aqueous calibration standards used in routine laboratory work. Supplied in a 100 ml plastic bottle, the standard is convenient for bench-top calibration, method checks and quality-control sequences. This ROTI®Calipure grade from manufacturer Carl ROTH is intended for laboratories that need a stable, clearly labelled Pt/Co colour reference without further dilution. Typical applications include drinking-water and wastewater colour grading, clear beverage and chemical intermediate control, and verification of spectrophotometric or comparator methods against the platinum-cobalt scale.
This article belongs on Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard Pt/Co, ROTI®Calipure 40 Hazen, 100 ml, plastic
What is this article?
Colour Standard Pt/Co, ROTI®Calipure 40 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?
