Redi-Dri™ – The World of Free-flowing Hygroscopic Products

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

实验方案

Bisphenol A Analysis in Food by SPME

Overcoated SPME fiber enables low-level BPA analysis in food via SPME-GC-MS/MS, meeting tighter migration limit regulations.

Questions

1–5 of 5 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

      Helpful?

  3. How long will material remain free-flowing after it is opened?

    1 answer

    1. While the exact amount of time your material will remain free-flowing can vary, this largely depends on the ambient storage conditions and how many times it is opened.

      Helpful?

  4. How does Redi-Dri™ help keep salts and buffers free-flowing?

    1 answer

    1. Redi-Dri™ products are specially handled and the bottle is specially designed to ensure that the product will remain dry without adding impurities or additives to the product. Ensuring that you receive the highest quality material that is easy to handle.

      Helpful?

  5. Are there any special storage conditions that must be maintained?

    1 answer

    1. No, Redi-Dri™ products can be stored under the same conditions as the equivalent non-Redi-Dri™ products.
