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

How do we open the thin metal container in which the chloroform (Item Number: 319988-2.5L) was shipped? Also, what is the primary packaging for this product?
1 answer-
The cannister is not considered the primary packaging; instead, it serves as an overpack, providing protective casing for the product.
1. To open the canister, a can opener can be used, unless the item features a flip-top, in which case the tab can be flipped up and pulled to pry open the top, similar to a soup can.
2. The primary packaging for this product consists of a 2.5L amber glass bottle with a red polypropylene cap, HDPE, and PTFE liner.Helpful?

Can you recommend a Solvent Extractor for organics from aqueous solution?
1 answer-
Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.
