Description
Nitric acid ROTIPURAN® Supra is a high-purity 69 % grade with the empirical formula HNO₃ and CAS number 7697-37-2. It offers a molar mass of 63,01 g/mol, a density range of 1,39 to 1,41 g/cm³ and a boiling point of 120 to 121 °C, supporting demanding analytical and sample-preparation workflows. The ROTIPURAN® Supra quality from manufacturer Carl ROTH is intended for trace-level work and reagent applications that require a well-characterised mineral acid. Typical laboratory uses include digestion of organic and inorganic matrices, acidification of samples and preparation of calibration solutions. The robust HDPE packaging aids safe storage and handling on the bench. This 69 % nitric acid provides a reliable option for laboratories focused on elemental analysis and environmental testing.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Nitric acid , ROTIPURAN® Supra, 69 %, 500 ml, HDPE
What is this article?
Nitric acid , ROTIPURAN® Supra, 69 %, 500 ml, HDPE is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
