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 답변-
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 to make 0.2M formic acid solution?
1 답변-
Assuming a 96% purity, to prepare 100mL of a 0.2 M solution, slowly add 0.786 mL of your stock solution to 25 mL deionized water. Adjust the final volume of solution to 100 mL with deionized water.
To prepare 500mL of a 0.2 M solution, slowly add 3.930 mL of your stock solution to 125 mL deionized water. Adjust the final volume of solution to 500 mL with deionized water.
See the link below to access the molarity calculator. Enter the desired volume, the lot specific product percentage, and the desired volume. Click the 'Calculate' button to get preparation instructions:
