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.

Application
- Buffers more than buffering agent: introducing a new class of stabilizers for the protein BSA.: This research highlights the use of MOPS sodium salt as a novel stabilizing agent for bovine serum albumin (BSA), extending its role beyond a simple buffering agent. The study demonstrates how MOPS sodium salt can improve the stability of BSA under various conditions, providing significant insights for biochemical applications and protein preservation (Gupta BS et al., 2015).
Packaging
- The current DRYPOUR®packaging configuration is in a 50L nestable drum
- 25KG-DP are the standard prepack offering
- Smaller volumes can be put in the same drum for variable configurations
- Improves operational efficiency by reducing material preparation time and increasing operator safety
- Minimizes caking of hygroscopic salts
- Offers triple protection: against moisture inside and outside, and against contamination
- This state-of-the-art design packaging system minimizes caking, thus significantly reducing the time needed for material preparation
- PE drum with our new tamper-evident seal, a polyethylene liner with integrated desiccant bags and a breathable interior Tyvek®liner
- Desiccant bags are firmly integrated into the polyethylene liner
- Triple protection delivers two invaluable results:
- Dramatically reduced caking
- No contamination risk from the desiccant

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

Hi I was wondering if this compound MOPs free acid and the MOPS Sodium Salt have an expiry date?
1 answer-
These products are not assigned an expiration date. They is assigned a recommended retest date of 2 years after the quality release date. A recommended retest date is the period of time during which the products are expected to remain within established stability specifications, provided that they has been stored under defined conditions. After the Retest Date, samples should be examined to ensure that the products are still in compliance with the established specifications.
