詳細

ポリスチレンは、スチレンを重合して作られる高分子量の合成ポリマーです。その性質は、耐久性、熱可塑性があり、疎水性です。

アプリケーション

ポリスチレン(PS)は、光学顕微鏡、細胞追跡および光学センサーの分野に応用できる、 色素ドープした蛍光PSナノ粒子合成の 前駆体として使用できます。

PSでキャップしたペロブスカイト粒子を形成することで、 ペロブスカイト成分を安定化できます。このPS被覆により、 有機成分の蒸発や水による腐食が抑制され、 ペロブスカイト膜の結晶自己修復が促進されます。

光学的に透明で、低コストで容易に製造できるため、in vitro細胞培養の基本的な基質として広く使用されています。

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

    1 回答
    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

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

    1 回答
    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.
