Unfortunately, the long term stability of the prepared solution has not been determined. However, prepared solutions are expected to be quite stable. Similar Sodium Carbonate/Bicarbonate 20X solutions are assigned a 2 year shelf life. Provided that solutions are stored refrigerated and not contaminated, a comparable shelf life is expected. Solutions should be observed for any changes in color and turbidity. Please see the link below to review the prepared 20X Concentrate product options:

Descrizione generale
Per lo più, il pH del tampone bicarbonato è attorno a 7,4. È il principale tampone dell′intestino tenue.[1]
Applicazioni
Il tampone carbonato-bicarbonato è stato usato per sospendere il campione di plasma umano liofilizzato per il saggio sul biofilm delle piastre di titolazione e il saggio sul biofilm delle celle di flusso.[2] È stato usato anche come tampone di rivestimento per piastre di microtitolazione prima del saggio immuno-assorbente legato a un enzima (ELISA).[3][4]
Il tampone preparato è adatto all′uso nelle procedure di rivestimento con proteine su piastre multipozzetto o provette di plastica.
Ricostituzione
Svuotare il contenuto di una capsula in 100 mL di acqua deionizzata e sciogliere. Il contenuto di una capsula fornisce 100 mL di tampone carbonato-bicarbonato 0,05 M, a pH 9,6 e 25 °C.

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

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