애플리케이션

Ethanol was used as dispersion medium for already prepared silver nanoparticles.[1]
It may be used in the following studies:
  • Hydrothermal synthesis of single crystal ZnO nanorod.[2]
  • Synthesis of N-(N′dodecylcarboxamidomethyl)N,N,dimethyl ammonio propane sulfonates.[3]
  • As solvent for cytofluorimetric analysis.[4]
  • Preparation of TiO2 colloid (particle size = 20nm).[5]

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

    1 답변
    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

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

    1 답변
    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.

  3. As this product is not denatured. Can we make it denatured by adding 1% Methanol in it. Request advice.

    1 답변
    1. It is possible to denature Ethanol via the addition of Methanol. The final Methanol concentration is generally above 1%, frequently in the range of 5 to 10%.

  4. Sehr geehrte Damen und Herren, ist der Ethanol 32221-M (puriss. p.a., absolute, ≥99.8% (GC)) vergällt / denaturiert oder unvergällt / nicht-denaturiert? Leider ist mir das weder von der Homepage noch vom SDB endgültig ersichtlich. Beste Grüße!

    1 답변
    1. This product is not denatured.

  5. Bonjour, Quelle est la différence entre la référence 32205-1L-M et la référence 32221-1L-M? Merci

    1 답변
    1. These products are physically identical with the same minimum purity specification. Product 32205-M is reagent grade which is suitable for general lab applications. It meets some of the analytical specifications of European Pharmacopoeia and testing includes trace analysis. Product 32221-1L-M is Puriss p.a. grade meaning the testing is also extensive and includes trace analysis. The quality of these products is comparable.
