Questions

1–3 of 3 Questions  

  1. What is the difference between the two product "Color Reference Solutions Ph.Eur. related to Ph.Eur Color intensity testing, analytical standard, Set of colors Y", article number 83883, and "Colour Reference Solutions Y" article number 1.000267?

    1 answer

    1. Products 1.00267.0001 and 83883-1SET-F both contain the seven yellow color reference standards (from Y1 to Y7). The 1.00267.0001 also comes with three empty sample cells, but no blank. The 83883-1SET-F comes with a blank or blind sample of 1% hydrogen chloride solution in water, but no additional empty cells. In both cases, the Y1-Y7 standards are prepared in accordance with chapter 2.2.2 "Degree of colouration of liquids" of the European Pharmacopoeia (Ph. Eur.).
      Those two products are typically available in different geographies. For example, as of early 2026, 1.00267.0001 cannot be ordered in North America, but 83883-1SET-F can be ordered in North America. Check with your local Customer Service group to see which one can be ordered in your geography.

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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
