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.

一般描述
玻璃羊毛塞通常用于GC进样口衬管中，以改善样品蒸发，和防止非挥发性物质进入色谱柱。它们还可用于填充的气相色谱柱、溶剂解吸管、热解吸管、以及吹扫捕集阱，以保留吸附床。
应用
- 不同因素对玻璃棉浓缩水样中主要猪病毒进行检测的影响评估：研究介绍了玻璃棉在过滤和浓缩环境样本中的病毒方面的作用，为公共卫生安全和环境监测做出了重大贡献（Fan et al., 2023）。
- 高温处理后纤维增强型二氧化硅气凝胶隔热性能的演变：研究了玻璃棉的隔热效果及其在高温下的耐久性，这对于其在高性能建筑围护结构和工业设施中的应用至关重要（Gao et al., 2023）。

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
