Description
Hydrofluoric acid ROTIPURAN® Ultra 48 % is a high-purity acid reagent with empirical formula HF, CAS number 7664-39-3 and EG nr. 231-634-8. Key physical data include a molar mass of 20,01 g/mol, density of 1,18 g/cm³ and boiling point of 108 °C. The product is It supports silicate and oxide digestion steps and related sample preparation in environmental analysis and elemental techniques such as AAS, ICP and IC, where controlled hydrofluoric acid concentration is required. ROTIPURAN® Ultra material from manufacturer Carl ROTH provides a defined 48 % grade for laboratories that specify ultra-pure mineral acids in method SOPs. Documented CAS, density and boiling point simplify risk assessment, method transfer and inventory control when working with HF-based matrices under appropriate laboratory safety procedures.

Questions about Hydrofluoric acid , ROTIPURAN® Ultra 48 %, 500 ml, plastic (FEP)
What is this article?
Hydrofluoric acid , ROTIPURAN® Ultra 48 %, 500 ml, plastic (FEP) 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.
