Étalons physico-chimiques

Les standards physicochimiques sont des matériaux de référence essentiels utilisés pour garantir la précision et la fiabilité de diverses mesures analytiques dans la recherche scientifique et les applications industrielles. Cette catégorie comprend une large gamme de standards tels que les standards de conductivité, les standards d'électrochimie et les standards et réactifs ICP-OES/ICP-MS, qui sont cruciaux pour les analyses élémentaires précises et les mesures de conductivité. Les solutions tampons de pH et les réactifs de carbone organique/inorganique total sont vitaux pour maintenir les niveaux de pH et mesurer la teneur en carbone dans les échantillons. Les standards de la Pharmacopée Européenne (EP), de la Pharmacopée des États-Unis (USP) et d'autres pharmacopées fournissent des points de référence pour le contrôle de qualité pharmaceutique. D'autres standards, tels que ceux de turbidité, de densité, de réfractométrie et de viscosité, garantissent des mesures précises des propriétés physiques. Les standards spécialisés, comme ceux pour l'industrie du vin, des produits laitiers et pétrochimiques, soutiennent le contrôle de qualité et la conformité réglementaire dans des secteurs spécifiques. Ces standards physicochimiques jouent un rôle crucial dans l'assurance de la validité et de la reproductibilité des résultats expérimentaux, soutenant une large gamme d'applications, de la surveillance environnementale aux tests pharmaceutiques et à la science des matériaux.

  • Reagecon Sulphuric Acid 1.0M (2.0N) Analytical Volumetric Solution (AVL)


    Reagecon's Sulphuric Acid 1.0M (2.0N) Analytical Volumetric Solution (AVL) is tested by an ISO 17025 Accredited Test Method (A2LA Ref: 6739.03). This product is a fully factorised; high purity; stable product; developed and tested for acid/base 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. Acid/base titrations; also called neutralisation titrations; are used to determine either the amount of acid/base in a sample or the substance that can be converted to an acid/base. - 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.
