Description
Colour Standard Pt/Co ROTI®Calipure 250 Hazen is a platinum-cobalt colour reference solution intended for calibration and control of colour determinations on the Hazen (APHA/Pt-Co) scale. Offered in a 100 ml plastic pack, it is designed for laboratories performing water testing, chemical quality assessment and routine colourimetry. Physical data include a density of 1,017 g/cm³ and a boiling point of 100 °C; the product is assigned UN number 3264. This ROTI®Calipure grade from manufacturer Carl ROTH delivers a defined 250 Hazen intensity, enabling reliable comparison of clear to moderately coloured samples by visual or instrumental methods. Typical applications include verification of photometers and colour comparators, method validation and ongoing quality control where stable Pt/Co reference values are required. The practical plastic bottle supports straightforward dispensing and bench-top use while helping preserve the standard for repeated analytical checks.
This article belongs on Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard Pt/Co, ROTI®Calipure 250 Hazen, 100 ml, plastic
What is this article?
Colour Standard Pt/Co, ROTI®Calipure 250 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?
The category is Analytical standards & reference materials. The sub-category is Spectroscopy & physical property standards. The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN) and Indicators & indicator solutions.
