Description
Ammonia solution ROTIPURAN® Supra 20 % is an aqueous alkaline reagent with empirical formula NH₃ + H₂O, CAS number 1336-21-6 and molar mass 17,03 + aq g/mol. Density ranges from 0,92 to 0,94 g/cm³, and the product is Available from manufacturer Carl ROTH, this ROTIPURAN® Supra grade is aimed at environmental analysis and AAS, ICP and IC standard applications as well as general reagent use. The 20 % ammonia solution supports pH adjustment, complexation steps, sample preparation and wet-chemical procedures that require a defined aqueous ammonia concentration. Identifiers include EG nr. 215-647-6 and UN number 2672 for correct classification and handling. HDPE packaging is practical for laboratory dispensing and storage of ammonia solution. Clear statement of concentration, CAS data and physical properties helps laboratories match the reagent to validated methods and safety instructions.

Questions about Ammonia solution , ROTIPURAN® Supra 20 %, 500 ml, HDPE
What is this article?
Ammonia solution , ROTIPURAN® Supra 20 %, 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.
