Opis ogólny

Maximum temperature of 200 °C.
Polytetrafluoroethylene (PTFE) or Fluorinated Ethylene Propylene (FEP) is a fluoropolymer which is the most lubricious polymer with low co-efficient of friction.[1] PTFE tubing is chosen due to its excellent hydrophobicity, chemical inertness, and ability to withstand high pressures.[2] It can be suitable to protect the optical fibres.[3]

Zastosowanie

PTFE tubing may be used to connect the gas lines to the ports during gas chromatography-mass spectrometry analysis of volatile organic compounds from potato tubers inoculated with Phytophthora infestans or Fusarium coeruleum.[4]

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.

  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
