Indicadores y soluciones volumétricas analíticas

Las soluciones volumétricas analíticas y los indicadores son estándares de referencia esenciales utilizados en análisis químicos precisos y procedimientos de laboratorio. Estas soluciones aseguran la exactitud en las mediciones cuantitativas, desempeñando un papel crucial en espectroscopía, cromatografía líquida de alta resolución (HPLC) y cromatografía de gases. Son fundamentales en diversos campos, incluyendo la bioquímica, la biología celular y molecular, y la ciencia de materiales. Los componentes clave incluyen ácidos, reactivos sintéticos y una variedad de Building Blocks orgánicos, como carbonilos y compuestos heterocíclicos. Estos estándares son vitales para asegurar el cumplimiento de las normativas ambientales y el control de calidad farmacéutico. Además, apoyan aplicaciones de investigación avanzada en áreas como la espectroscopía NMR, la síntesis de péptidos y el desarrollo de ingredientes farmacéuticos activos (APIs). La fiabilidad y precisión proporcionadas por estas soluciones volumétricas e indicadores son indispensables para la investigación científica y las aplicaciones industriales, garantizando la validez y reproducibilidad de los resultados experimentales.

  • Reagecon Silver Nitrate 0.1M (0.1N) Analytical Volumetric Solution (AVL)


    Reagecon's Silver Nitrate 0.1M (0.1N) 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 precipitation (argentometric) 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. Precipitation titrimetry is based on reactions that yield compounds of limited solubility. - 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.

  • Reagecon Calcium Acetate 1.0M Analytical Volumetric Solution (AVL)


    Reagecon's Calcium Acetate 1.0M Analytical Volumetric Solution (AVL) is a fully factorised, high purity, stable product, developed and tested for complexometric 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.  Complexometric titrimetry is based on the reaction of a metal ion with a ligand to form a complex. Methods have been developed, validated and published for detection or quantification of almost every metal in the periodic table using EDTA complexation. - 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.

  • Reagecon Copper II Sulphate 0.1M (0.1N) Analytical Volumetric Solution (AVL)

    CAS:
    Reagecon's Copper II Sulphate 0.1M (0.1N) 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.
