General description

Sodium carbonate is a volumetric standard manufactured under stringent conditions and measured with the highest possible precision. Its mass fraction is determined by potentiometric titration, and it is qualified in a DIN EN ISO/IEC 17025 accredited laboratory.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

In our effort to be more sustainable, we′re going digital with COAs-download them directly from our website. Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

Application

It is used as a certified reference material (CRM) for the standardization of volumetric solutions in acidimetric titrations, according to USP and Ph. Eur.

Biochem/physiol Actions

Componente tampone, può essere usato per rimuovere le proteine di membrana periferiche.

Features and Benefits

  • Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
  • Certified reference material according to ISO 17034
  • High-purity material traceable to NIST SRMs
  • Measured in a DIN EN ISO/IEC 17025 accredited laboratory

Domande

1–2 di 2 domande  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 risposta
    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 risposta
    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
