Description
Refractive index standard ROTI®Calipure with a certified value of 1,38779 at 20 °C is a calibration liquid for refractometry and related optical measurements. The product is supplied as a 15 ml fill in glass and shows a density of 0,68 to 0,69 g/cm³, a boiling point of 98,2 to 98,4 °C, and a flash point of −4 °C. These physical data support routine verification of laboratory refractometers and quality-control checks where a stable refractive index reference is required. Available from manufacturer Carl ROTH under the ROTI®Calipure line, the standard helps laboratories maintain measurement traceability in analytical, chemical, and process-control environments. The glass pack format is suitable for bench use and controlled storage within calibration workflows. Users can apply the stated refractive index at 20 °C when qualifying instruments or confirming day-to-day performance. Clear boiling-point, density, and flash-point information from the source data assist safe handling and documentation in regulated or accredited laboratory settings that rely on optical standards.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Refractive index standard, ROTI®Calipure, 1,38779 (20 °C), 15 ml, glass
What is this article?
Refractive index standard, ROTI®Calipure, 1,38779 (20 °C), 15 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?
