Description
Nitric acid 65 %, ROTIPURAN® est un réactif analytique de haute pureté fourni en qualité p.a., ISO avec une teneur maximale en mercury de 0.005 ppm Hg. Identifié par le numéro CAS 7697-37-2 et la formule empirique HNO₃, il a une masse molaire de 63.01 g/mol, une densité de 1.39 à 1.41 g/cm³ et un point d'ébullition de 120 à 121 °C. Cet acide minéral concentré est largement utilisé en analyse environnementale, digestion par chimie humide, préparation d'échantillons et flux de travail généraux de laboratoire qui exigent des blancs pauvres en métaux et des performances analytiques reproductibles. Sa concentration définie et son profil d'impuretés contrôlé le rendent adapté à la titration, aux étapes d'oxydation et à la digestion de matrice lorsqu'une force acide constante est essentielle. Manipulez-le et conservez-le selon la pratique de sécurité de laboratoire pour les acides oxydants forts.

Questions about Nitric acid 65 %, ROTIPURAN®, p.a., ISO, max. 0.005 ppm Hg, 1 l, verre
What is this article?
Nitric acid 65 %, ROTIPURAN®, p.a., ISO, max. 0.005 ppm Hg, 1 l, verre 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.
