Description
Standard for Total Acid Number (TAN) ROTI®Calipure 2,5 mg KOH/g is a calibration standard intended for laboratory titration of total acid number. The preparation is offered as a 50 g fill in glass and supports TAN and TBN titration procedures used in analytical quality control. Density is stated at approximately 1 g/cm³, with a boiling point around 100 °C, allowing predictable behaviour during everyday laboratory handling. This ROTI®Calipure standard from manufacturer Carl ROTH supplies a nominal value of 2,5 mg KOH/g for checking titrator performance, method suitability and measurement consistency when determining acid number in oils, lubricants and similar matrices. It is aligned with titration applications, especially TAN/TBN analysis, where a fixed reference level simplifies calibration and control work. The glass container format is practical for bench storage and transfer between measurement series. Together these attributes make the product a useful working standard for industrial and research laboratories that require reproducible total acid number references without complex sample preparation.

Questions about Standard for Total Acid Number (TAN), ROTI®Calipure 2,5 mg KOH/g, 50 g, glass
What is this article?
Standard for Total Acid Number (TAN), ROTI®Calipure 2,5 mg KOH/g, 50 g, 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?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
