Solutions et indicateurs volumétriques analytiques
Les solutions volumétriques analytiques et les indicateurs sont des standards de référence essentiels utilisés dans les analyses chimiques précises et les procédures de laboratoire. Ces solutions garantissent l'exactitude des mesures quantitatives, jouant un rôle crucial dans la spectroscopie, la chromatographie liquide haute performance (HPLC) et la chromatographie en phase gazeuse. Elles sont fondamentales dans divers domaines, y compris la biochimie, la biologie cellulaire et moléculaire, et la science des matériaux. Les composants clés incluent des acides, des réactifs synthétiques et une variété de Building Blocks organiques tels que les carbonyles et les composés hétérocycliques. Ces standards sont vitaux pour assurer la conformité aux normes environnementales et le contrôle de qualité pharmaceutique. De plus, ils soutiennent les applications de recherche avancée dans des domaines tels que la spectroscopie RMN, la synthèse de peptides et le développement d'ingrédients pharmaceutiques actifs (APIs). La fiabilité et la précision fournies par ces solutions volumétriques et indicateurs sont indispensables pour la recherche scientifique et les applications industrielles, garantissant la validité et la reproductibilité des résultats expérimentaux.

Reagecon Potassium Iodate 0.05M (0.3N ) Analytical Volumetric Solution (AVL)
Reagecon's Potassium Iodate 0.05M (0.3N ) Analytical Volumetric Solution (AVL) is a fully factorised, high purity, stable product, developed and tested for oxidation/reduction titrations. This Analytical Volumetric Solution, also called titrant, standard titrant or standard solution, is tested to a specification of ± 0.1%. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations, or more commonly automatic titrations, to determine the end points by detection of any of several properties. Oxidation/reduction titrations depend on changes in the electropotential of the oxidation reduction system and always involves a reaction between an oxidising and reducing pair. - Titration is a rapid, economical and versatile analytical tool. This Reagecon titrant is accurate, stable, reproducible and fully factorised. Titrations performed with this product, exhibit defined stoichiometry, are quantitative, establish an equilibrium that is definitive and fast and provide unambiguous results. Stability is proven (either opened or unopened) for the shelf life of this product.Couleur et forme :LiquidN-(Trimethylsilyl)acetamide
