Questions

1–9 of 9 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

  3. About TedlarGasSamplingBag(1L), do you have appropriate PVC tube (3/16" ID) or any kind of tube to connect the bag to sampling point? General one is very slightly wider than nozzle on it.

    1 answer

    1. The PVC laboratory tubing that has an (I.D.) of 3/16" is Product Z280364-1PAK. However, it must be noted that the polypropylene valve stem is 3/16" in outside diameter (O.D.) which means that the recommended tubing must have 1/4" (I.D.) which is Product Z280372-1PAK.

  4. For 24633 product, what is the maximum temperature and pressure the bag can withstand? and is it in transparent form?

    1 answer

    1. Tedlar® films are rated for continuous use from -72°C to 107°C (-98°F to 225°F). This Tedlar® PVDF film is transparent. The Tedlar film has a tensile strength of 8000 psi while the recommended fill pressure is 17.7 psi. The maximum fill volume should be limited to 75 - 80 % to allow for pressure changes.

  5. Is there any recommendation regarding how often the septum can be pierced with a needle for removal of gas, until the septum loses its integrity?

    1 answer

    1. The septum is located at the base flange of the valve with the bag film below. The septum does not come into contact with the sample. The septum allows repeated punctures with syringes without leakage. The number of times the fluoropolymer septum may be punctured before it loses its integrity had not been determined. A small guage needle should assure maximum life of the septum.
