How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

We would like to know if this methylcellulose is derived from bacteria or from plants? And if it's possible, is it known the size of the pores of metlhylcellulose hydrogels, produced with this specific methylcellulose?
1 answer-
Source origin details can vary from lot to lot. Cellulosic material tends to be derived from wood pulp. Hydrogel pore size can vary depending on the conditions used. Please consult scientific literature for specific guidance.

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 I make up 25cP, 50cP, 100cP viscosity solutions with the M0262 methyl cellulose?
1 answer-
The viscosity of this product can reach 300-560 cP when forming a 2% solution in water at 20 °C. To prepare 25 cP, 50 cP, and 100 cP viscosity solutions, the 2% solution must be further diluted. In general, the viscosity of a solution will decrease with dilution, but the relationship is not always strictly proportional. Therefore, it is essential to use a viscometer to accurately measure the viscosity after each dilution step to achieve the desired viscosity levels.
