Allgemeine Beschreibung

Nanosized aluminum oxide, also called nano alumina or Al2O3 nanoparticles, is a form of aluminum oxide with a small particle size and high specific surface area. Our aluminum oxide nanoparticles have a particle size less than 50 nm. The nanoparticles are suspended in isopropyl alcohol (IPA) to facilitate its dispersion and use. Nano alumina exhibits unique bio-physicochemical properties, including high surface area, high hardness, thermal stability, and biocompatibility. In the field of catalysis, it servesas efficient catalyst supports, enhancing reaction rates and selectivity. They also exhibit remarkable dielectric properties, making them valuable for electronic and optoelectronic devices. Additionally, Al2O3 NPs have demonstrated promising results in biomedical applications, including drug delivery systems, biomedical imaging, biosensing, and tissue engineering. They are also key components in advanced coatings, energy storage systems, environmental remediation, optoelectronics, photonics, and personal care products.

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.

  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
