Standard fisico-chimici

Gli standard fisicochimici sono materiali di riferimento essenziali utilizzati per garantire la precisione e l'affidabilità di varie misurazioni analitiche nella ricerca scientifica e nelle applicazioni industriali. Questa categoria include una vasta gamma di standard come gli standard di conducibilità, gli standard di elettrochimica e gli standard e reagenti ICP-OES/ICP-MS, che sono cruciali per analisi elementari precise e misurazioni della conducibilità. Le soluzioni tampone di pH e i reagenti per il carbonio organico/inorganico totale sono vitali per mantenere i livelli di pH e misurare il contenuto di carbonio nei campioni. Gli standard della Farmacopea Europea (EP), della Farmacopea degli Stati Uniti (USP) e di altre farmacopee forniscono punti di riferimento per il controllo di qualità farmaceutico. Altri standard come quelli di torbidità, densità, rifrattometria e viscosità assicurano misurazioni precise delle proprietà fisiche. Gli standard specializzati, come quelli per le industrie del vino, lattiero-casearia e petrolchimica, supportano il controllo di qualità e la conformità normativa in settori specifici. Questi standard fisicochimici giocano un ruolo cruciale nel garantire la validità e la riproducibilità dei risultati sperimentali, supportando un'ampia gamma di applicazioni, dalla monitoraggio ambientale ai test farmaceutici e alla scienza dei materiali.

  • Reagecon Silver Nitrate 0.01M (0.01N) Analytical Volumetric Solution (AVL)


    Reagecon's Silver Nitrate 0.01M (0.01N) Analytical Volumetric Solution (AVL) 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.
