一般說明

我们致力于为您带来更加绿色的替代产品,这些产品遵守一项或多项绿色化学12项原则。乙醇是一种绿色环保溶剂,符合“更安全的溶剂和助剂”以及“使用可再生原料”的原则。点击此处了解更多信息。

LiChrosolv溶剂具有较高的紫外线透射率、低颗粒数、低酸碱度和低蒸发残留量,因而是可重现分离的理想选择。由于在分析型HPLC中分离通常在梯度条件下进行,因此我们提供“梯度””和“等度”级溶剂。这使得所使用的溶剂的梯度影响最小化。

應用

乙醇可用作溶剂:
  • 制备甲氰菊酯和联苯菊酯的储备标准和工作溶液。[1]
  • 绿色分析化学中的替代、可持续溶剂。 [2]

準備報告

产品已经过0.2 μm滤器过滤

其他說明

1在瑞士分发和使用乙醇需要瑞士联邦酒精管理局的许可证。
欢迎探索各式各样的实验室安全配件和设备,以安全操作溶剂,在首次使用时就能获得较高的安全水平。

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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
