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.

一般說明
方法：试纸比色法，0 - 25 - 50 - 100 - 200 - 500 mg/L Cl2, MQuant®
MQuant®氯测试试纸适用于快速测定主要用于食品工业的较高浓度的含氯消毒剂。在试纸上，游离氯将橙色化合物氧化为紫色染料。通过目测比较试纸的反应区和色标区域，可半定量测定氯浓度。如要定量测定或测定总氯，请选择我们的Reflectoquant®或Spectroquant®氯测试产品系列。
可持续性设计优点：
通过探索改善产品组合中现有产品的方法，我们始终一致地展现出我们对地球和可持续未来的承诺。最近我们评估了当前的 MQuant®试纸产品线，目的是为了发现减少环境影响同时不影响产品性能的重要机会。

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

Can this product be used to measure chlorine in cell culture media? If not, which other product could be used in this setting and is anything known on how the cell culture media might interfere with the measurement?
1 answer-
Specific chlorine tests for samples like culture media are not provided in the portfolio. The usage instructions for several chlorine test products indicate their use with wastewater, bleaching solutions, and disinfectants samples. It is expected that an aqueous sample such as culture media may be measurable with a standard chlorine test. Determining the suitability of a specific product for the intended application and matrix is the responsibility of the end user.
