Description
Refractive index standard ROTI®Calipure 1,44468 (20 °C) is a defined calibration liquid in a 15 ml glass pack for laboratory refractometry. The refractive index value at 20 °C supports accurate verification and adjustment of refractometers used in analytical chemistry, quality control and training laboratories. Reported physical data include a density of 0,794 g/cm³, a flash point of −4 °C and a boiling point of approximately 98 °C, which assist risk assessment and method write-ups. This ROTI®Calipure standard from manufacturer Carl ROTH is intended for users who need a higher nD reference point within a compact glass format. Typical applications cover instrument qualification before measurement series, cross-checks between devices and educational demonstrations of optical calibration. The 15 ml glass unit is convenient for controlled dispensing and storage within calibration kits. UN number 3295 applies for transport. Choose this grade when a refractive index of 1,44468 at 20 °C and small-volume glass packaging are required for dependable everyday refractometer calibration.

Questions about Refractive index standard, ROTI®Calipure, 1,44468 (20 °C), 15 ml, glass
What is this article?
Refractive index standard, ROTI®Calipure, 1,44468 (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?
