General description

This whole volume certified reference material (CRM) is prepared and certified according to ISO 17034 and ISO/IEC 17025. The specific conductance value of 147 ± 1 µmhos/ cm is measured using SI and higher order standards from NIST through an unbroken chain of comparisons.

The certificate of analysis (CoA) includes information such as traceability, uncertainty, stability, homogeneity and health & safety.

This product is delivered in a 500 mL HDPE bottle.

Application

Used as a calibration standard for conductivity meter verification.

Questions

1–3 of 3 Questions  
  1. 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

  2. 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

  3. Bonjour, la température de référence n'apparaît pas sur le COA. Comment savoir si c'est bien 25°C. Cordialement.

    1 answer
    1. The certified conductivity value associated with Product No. COND147 is measured and reported at 25 °C.
