Description
Sodium thiosulphate solution ROTI®Volum is a volumetric standard solution at 0,0125 mol/l (0,0125 N) intended for analytical laboratory use. Bearing the empirical formula Na₂O₃S₂, this sodium thiosulphate preparation supplies a defined concentration suited to volumetric analysis and titration procedures that specify this normality. Density is given as approximately 1 g/cm³, with a boiling point of about 100 °C, supporting predictable handling in standard laboratory environments. The product is packed as 1 pc in the ROTI®Volum ampoule presentation and weighs 0,101 kg. It belongs to the volumetric solutions in ampoules series from manufacturer Carl ROTH, within the analytical chemicals category for standardised reagents. The sealed ampoule format maintains the concentrate until the working solution is prepared according to laboratory protocols. Concentration, formula, and physical data follow the manufacturer description, facilitating integration into established quantitative methods. This single-piece unit is practical for controlled use in routine titration series, method support, and quality-oriented analytical workflows requiring 0,0125 N sodium thiosulphate solution.

Questions about Sodium thiosulphate sol. ROTI®Volum, 0.0125 mol/l - 0.0125 N volumetric solution
What is this article?
Sodium thiosulphate sol. ROTI®Volum, 0.0125 mol/l - 0.0125 N volumetric solution is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Volumetric standard solutions (titration), inside Analytical standards & reference materials, in Lab chemicals.
A volumetric standard solution is a reagent of stated concentration for titration, such as a stated molarity of acid, base or silver nitrate. The factor or the exact titre is on the certificate. Using the nominal molarity when a factor is printed is a systematic error.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
