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.

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

Is the item monodispersed Polypropylene glycol?
1 回答-
This product is tested for Mn and Mw. The polydispersity index (PDI) can be calculated by dividing Mw by Mn. A value of 1 would indicate a monodisperse polymer. For a recent lot (sample COA: https://www.sigmaaldrich.com/certificates/sapfs/PROD/sap/certificate_pdfs/COFA/Q14/81380-BULKBCCK6778.pdf), the Mw was tested to be 3116 and the Mw was tested to be 3009, equating to a PDI of 1.04, which is very close to being considered monodisperse. The Mw and Mn values do not have specifications associated with them but, historically, they tend to be similar to each other for this polymer.
