Description
Sodium hydroxide solution ROTIPURAN® min. 32 %, p.a. is an analytical-grade aqueous NaOH solution The empirical formula is NaOH with molar mass 40,01 g/mol; density is 1,35 g/cm³ and boiling point 120 °C. It is identified by CAS number 1310-73-2 and EG nr. 215-185-5 and carries UN number 1824. This minimum 32 % p.a. grade supports analytical chemistry tasks that require a defined sodium hydroxide solution, including food analysis and nitrogen determination according to Kjeldahl where alkaline reagents are specified. Physical data help laboratories plan handling, storage logistics and method documentation. Intended for professional laboratory environments only, ROTIPURAN® p.a. sodium hydroxide solution offers a clear concentration and purity designation for analytical workflows without extending beyond the stated min. 32 % p.a. specification.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Sodium hydroxide solution, ROTIPURAN® min. 32 %, p.a., 1 l, plastic
What is this article?
Sodium hydroxide solution, ROTIPURAN® min. 32 %, p.a., 1 l, plastic 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?
