Description
Colour Standard ROTI®Calipure ASTM A3 is a ready-to-use liquid reference for visual colour recognition and colour number determination according to the ASTM scale. Supplied as 100 ml in glass, it enables reliable side-by-side comparison when laboratories assess the colour of oils, fuels and similar materials. Defined physical properties include a density of approximately 0,757 g/cm³, a flash point of 71 °C and a boiling point of 205,5 °C, supporting safe handling and clear product identification in daily quality-control workflows. The ROTI®Calipure ASTM A3 grade from manufacturer Carl ROTH is designed for determination of physical properties where stable visual colour matching is required. Laboratories employ these standards to set reference colours, confirm colour numbers and improve reproducibility between operators, instruments and production lots. The glass packaging is practical for bench work and helps protect the contents during storage and dispensing. Application fields include analytical chemistry, petrochemical laboratories and industrial quality assurance where ASTM colour grading underpins specification checks and process monitoring.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard, ROTI®Calipure ASTM A3, 100 ml, glass
What is this article?
Colour Standard, ROTI®Calipure ASTM A3, 100 ml, glass 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.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
