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

Interest in utilizing biodegradable polymers for biomedical applications has grown since the 1960s.
Synthetic aliphatic polyesters dominate resorbable biomaterials in clinical use.
商业生物材料已停滞不前超过30年的时间，因为很少有材料能够成功地从实验台过渡到临床使用。合成型脂族聚酯因其悠久的历史和获得美国食品药品监督管理局（FDA）批准的记录，一直在可吸收生物材料领域占据主导地位。
AliAliphatic polyesters, including polylactide and polyglycolide, are biodegradable polymers widely used in medical applications.

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.
