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.

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

Could you provide TGA results of these GO? I need a high thermal stability GO like 300-400 stable.
1 answer-
Unfortunately, thermogravimetric analysis (TGA) is not performed on this material. The decomposition temperature has not been established. Please see the link below to review an article which suggests that, in general, graphene oxide has a decomposition range by TGA from approximately 125 - 200°C.

How can graphene oxide (P/N: 796034) be homogenized in a PBS solution?
1 answer-
The product 796034 is edge functionalized graphene. One method to homogenize it is to use a regular lab ultrasonic bath. The appropriate sonication time depends on the machine power, typically around 15-20 minutes for a 100 Watts ultrasonic bath. If the dispersion is not as expected, the sonication process can be repeated.
Another alternative is to use a homogenizer/cell crasher. A homogenizer with 400-600 Watts is recommended, and it's suggested to set the homogenizer to sonicate for 3 seconds and then pause for 1.5 or 2 seconds, with a total sonication time of 15-20 minutes. Similarly, if the powder is not fully dissolved, the experiment may be repeated.
