Allgemeine Beschreibung

Die Redi-Dri™-Technologie vermeidet Klumpenbildung und die Notwendigkeit für komplizierte Verfahren, um Ihre Salze rieselfähig zu halten, entfällt. Ihre Salze trocken zu halten führt durch genauere Messungen und leichter zu handhabende Salze und Puffer zu besseren Ergebnissen. Statt Ihre Salze in einem Ofen oder Exsikkator zu trocknen oder sie von Hand auseinanderzubrechen, sorgt Redi-Dri™ dafür, dass Ihre Salze über Monate hinweg anwenderfreundlich bleiben, ohne dass sie sich über Antiklumpmittel Gedanken machen müssen. Selbst nach wiederholtem Öffnen können Sie sich sicher sein, dass Ihre Ergebnisse immer genau sind. Redi-Dri™ spart Ihnen Zeit, Energie und Geld, indem es Ihre Salze länger einsatzfähig hält.

Anwendung

Natriumchlorid wird für die Herstellung von Tris-gepufferter Kochsalzlösung, phosphatgepufferter Kochsalzlösung, MPM-2 (mitotisches Protein, monoklonal 2)-Zelllysepuffern, Immunpräzipitations-Waschpuffern, LB (Luria-Bertani)-Medien und Dialysepuffern verwendet.

Leistungsmerkmale und Vorteile

  • Erhöhte Effizienz – Minimiert Zeit- und Arbeitsaufwand bei der Auflockerung von verhärtetem Pulver
  • Sicherheit – Verhindert Risiken beim Lösen von Klumpen mit hartem Werkzeug
  • Wirtschaftlichkeit – Schnellere Vorbereitung und Solvatation erhöhen Produktivität und reduzieren Kosten
  • Garantierte Qualität – Hervorragende, von Fachexperten geprüfte Qualität ohne Rieselhilfsmittel
  • Unterschiedliche Mengen – Erhältlich in Kleinstmengen für die Forschung bis zu Mengen im Produktionsmaßstab

Questions

1–5 of 5 Questions  

  1. 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

  2. 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/449/386/product-dating-information-mk.pdf

  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.
