If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
El método corresponde a la DIN ISO 15705 y es análogo a los de la EPA 410.4, la APHA 5220 D y la ASTM D1252-06 B.
La demanda química de oxígeno (DQO) es una medida de la cantidad de oxígeno consumido durante la oxidación de la materia orgánica, lo que proporciona una clara indicación de la calidad de una fuente de agua, y es sin duda uno de los parámetros más importantes en el análisis de las aguas (residuales). Nuestros ensayos de DQO Spectroquant® le permiten cuantificar con precisión los niveles de DQO de su muestra.
Seleccione el intervalo de medición adecuado para sus requisitos de aplicación en nuestra amplia gama de ensayos de DQO Spectroquant® .
Los ensayos en cubeta Spectroquant® vienen con cubetas redondas de 16 mm precargadas y todos los reactivos necesarios para realizar el análisis de acuerdo con el folleto de instrucciones suministrado.
Todos nuestros kits de ensayo en cubeta y con reactivos Spectroquant® están equipados con el exclusivo Live ID (código de barras en 2D), que permite el reconocimiento perfecto del método y contiene información esencial como el número de lote, la fecha de caducidad y las actualizaciones de calibración automáticas.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
