Estándares fisicoquímicos
Los estándares fisicoquímicos son materiales de referencia esenciales utilizados para garantizar la precisión y fiabilidad de diversas mediciones analíticas en la investigación científica y aplicaciones industriales. Esta categoría incluye una amplia gama de estándares como los estándares de conductividad, los estándares de electroquímica y los estándares y reactivos de ICP-OES/ICP-MS, que son cruciales para análisis elementales precisos y mediciones de conductividad. Las soluciones tampón de pH y los reactivos de carbono orgánico/inorgánico total son vitales para mantener los niveles de pH y medir el contenido de carbono en las muestras. Los estándares de la Farmacopea Europea (EP), la Farmacopea de los Estados Unidos (USP) y otras farmacopeas proporcionan puntos de referencia para el control de calidad farmacéutico. Otros estándares como los de turbidez, densidad, refractometría y viscosidad aseguran mediciones precisas de propiedades físicas. Los estándares especializados, como los de la industria del vino, lácteos y petroquímica, apoyan el control de calidad y el cumplimiento normativo en sectores específicos. Estos estándares fisicoquímicos desempeñan un papel crucial en garantizar la validez y reproducibilidad de los resultados experimentales, apoyando una amplia gama de aplicaciones, desde el monitoreo ambiental hasta las pruebas farmacéuticas y la ciencia de materiales.

Reagecon's Sulphuric Acid 0.025M (0.05N) 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.
