Description
Refractive index standard ROTI®Calipure 1,65808 (20 °C) is a laboratory calibration reference for refractometry, supplied in a 15 ml glass pack. It provides a defined refractive index of 1,65808 at 20 °C, supporting instrument verification, routine checks and consistent optical measurement practice in analytical and research environments. Accompanying physical data include a density of 1,482 g/cm³, a flash point of 67 °C and a boiling point of 281 °C, giving clear context for handling by trained laboratory personnel. Offered from manufacturer Carl ROTH within the ROTI®Calipure line, the standard is intended for professional use where reliable refractive-index values are required for quality control and method support. The compact glass presentation suits bench-top calibration workflows and helps laboratories maintain comparable performance across instruments and operators. It fits chemistry, materials and life-science settings that depend on precise refractive index determination and can be integrated into existing calibration schedules without unnecessary complexity or additional process steps.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Refractive index standard, ROTI®Calipure, 1,65808 (20 °C), 15 ml, glass
What is this article?
Refractive index standard, ROTI®Calipure, 1,65808 (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?
