Description
Sulphuric acid ROTIPURAN® Supra is a 95 % high-purity mineral acid with the empirical formula H₂SO₄ and CAS number 7664-93-9. It is characterised by a molar mass of 98,08 g/mol, a density of 1,84 g/cm³ and a boiling range of 295 to 315 °C, making it suitable for demanding laboratory and analytical applications. The ROTIPURAN® Supra grade from manufacturer Carl ROTH is selected where low contaminant levels and consistent concentration are important. Typical uses include sample digestion, dehydration reactions, acidification steps and preparation of calibration media. The dense, concentrated liquid form allows accurate volumetric handling when appropriate safety measures are observed. This 95 % sulphuric acid offers a reliable, well-specified option for research and routine inorganic chemistry laboratories.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Sulphuric acid , ROTIPURAN® Supra, 95 %, 500 ml, HDPE
What is this article?
Sulphuric acid , ROTIPURAN® Supra, 95 %, 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.
