Description
Nitric acid ROTIPURAN® Supra est une qualité de haute pureté à 69 % avec la formule empirique HNO₃ et le numéro CAS 7697-37-2. Il offre une masse molaire de 63.01 g/mol, une plage de densité de 1.39 à 1.41 g/cm³ et un point d'ébullition de 120 à 121 °C, ce qui soutient des flux de travail analytiques et de préparation d'échantillons exigeants. La qualité ROTIPURAN® Supra du fabricant Carl ROTH est destinée aux travaux à l'état de traces et aux applications de réactif qui exigent un acide minéral bien caractérisé. Les usages typiques en laboratoire comprennent la digestion de matrices organiques et inorganiques, l'acidification d'échantillons et la préparation de solutions d'étalonnage. L'emballage HDPE robuste favorise un stockage et une manipulation sûrs sur la paillasse. Cette nitric acid à 69 % offre une option fiable pour les laboratoires axés sur l'analyse élémentaire et les essais environnementaux.

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 Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.
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 Solvants. The sub-category is Solvants de qualité analytique (p.a.). The catalogue is Produits chimiques.
