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.

Method
In weakly acidic solution free chlorine reacts with diethyl-p-phenylenediamine (DPD) to form a red-violet dye. In the presence of potassium iodide, also combined chlorine is measured in this reaction. The chlorine concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation.
The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
Using the refill pack 1.14803 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.

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
