Description
Colour Standard ROTI®Calipure Gardner 18 is a defined reference preparation for visual colour number determination on the Gardner scale. Supplied as a 100 ml glass unit, it supports routine colour recognition and physical-property assessment in analytical and quality-control laboratories. The standard exhibits a density of 2,541 g/cm³ and a boiling point of 100 °C, making it suitable for bench-top comparison methods used with coatings, oils, resins and related materials. Laboratories performing colour number determination can use this Gardner 18 point to verify visual scales, train operators and maintain consistent day-to-day evaluation. Offered in the ROTI®Calipure range from manufacturer Carl ROTH, the preparation fits established workflows for determination of physical properties and visual colour recognition without requiring instrumental colour measurement. The glass packaging is convenient for reference libraries and repeated visual checks. Integration into existing Gardner-scale protocols helps standardise results across batches and operators while remaining straightforward to handle in everyday laboratory practice.
This article belongs on Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard, ROTI®Calipure Gardner 18, 100 ml, glass
What is this article?
Colour Standard, ROTI®Calipure Gardner 18, 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?
