Descripción general

Trizma® base is a basimetric standard used in biochemistry and molecular biology. It may be used as a buffer or as a component of mixed buffer formulations. It is essentially stable, relatively non-hygroscopic and has a high equivalent weight.[1][2]

Aplicación

Trizma® base can be used as a buffer:
  • In the evanescent absorption analysis of NADPH.[3]
  • In the autoxidation studies of oxymyoglobin.[4]

Otras notas

Los valores de pH de todas las disoluciones tampón son dependientes de la temperatura y la concentración. Para los tampones Tris, el pH aumenta alrededor de 0,03 unidades por °C de disminución de la temperatura, y disminuye 0,03-0,05 unidades al ser diluido por 10.
Para aplicaciones precisas, debe utilizarse un peachímetro cuidadosamente calibrado con un electrodo de vidrio/calomelano combinados.

Questions

1–2 of 2 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
