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

500ml 기준 1000ppm Ga3 stock을 만들라고 하는데 이때 본제품의 Ga3 가루를 0.59g 첨가하고 용액을 다 에탄올로 채워야할까요?? 어떤 제품은 에탄올 조금에 증류수로 채우라하고 어떤 제품은 에탄올로만 만들어야한다는데 본 제품은 어떤식으로 만들어야하나요?

It is recommended to dissolve this product at 50mg/ml in pure Ethanol. From there, it can be diluted with an aqueous buffer or medium to the required working concentration.
