Description
Colour Standard ROTI®Calipure Gardner 4 is a liquid reference solution for colour number determination on the Gardner colour scale. Delivered in a 100 ml glass pack, it supports visual colour recognition together with laboratory determination of physical properties. It is characterised by a density of 1,009 g/cm³ and a boiling point of 100 °C, parameters that describe its behaviour under normal laboratory conditions. Gardner colour standards enable side-by-side visual comparison so that sample colour can be assigned consistently to a defined scale position. This ROTI®Calipure colour standard from manufacturer Carl ROTH supplies a practical Gardner 4 reference for structured colour number determination. The 100 ml glass format is convenient for repeated visual inspections, method verification and quality-control routines. Explicit Gardner 4 marking aids correct scale placement and clear documentation of results. The standard can be incorporated into existing visual colour recognition and physical-property assessment procedures used in professional analytical laboratories.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Colour Standard, ROTI®Calipure Gardner 4, 100 ml, glass
What is this article?
Colour Standard, ROTI®Calipure Gardner 4, 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?
