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.

应用
- 表面活性剂分子动力学研究：Dong等人通过分子动力学模拟研究了表面活性剂对甲烷和正癸烷相互作用的影响。该研究为正癸烷在提高表面活性剂在采油和环境修复过程中的性能方面的应用提供了见解（Dong et al.， 2024）。
- 界面吸附研究：Ruwoldt等人探索了油溶性硫酸盐木质素的界面吸附特性及其稳定油包水乳液的能力，其中正十烷作为模型碳氢溶剂起着至关重要的作用，有助于理解乳液稳定性和木质素-溶剂在工业应用中的相互作用（Ruwoldt等人，2024）。
- 半导体应变计在岩土工程中的应用：Mikhaltsevitch和Lebedev利用半导体应变计测量砂岩弹性模量的有效应力系数。在这些实验中，正癸烷可能被用作模拟天然碳氢化合物环境的流体介质，从而提高地球物理评估的准确性（Mikhaltsevitch et al., 2024）。

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.
