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 468 mV Redox Oxidation/Reduction (ORP) Standard at 25°C in Twin Neck
This Reagecon's 468 mV (± 5mV) Standard acts as a Control or Reference Material. This is because Redox Oxidation/Reduction (ORP) is an absolute measurement and the sensing electrode does not require calibration. This Standard verifies the functionality of the sensing and reference electrode; the analysts technique; environmental conditions and the operation of the measuring meter. The value of 468 mV quoted refers to the potentials of the platinum electrode v Ag/AgCl reference electrode. - Reagecon produces a complete range of high-quality Redox Standards for the control; validation or qualification of Redox measurement. - Very high specification (± 5mV). - Manufactured to exacting specifications with an extended shelf life and stability; even after opening the bottle. - All products are tested with proven verifiable accuracy and fully budgeted uncertainty of measurement.Couleur et forme :LiquidReagecon pH 3.00 Citrate 0.25M Buffer Solution according to European Pharmacopoeia (EP) Chapter 4 (4.1.3)
