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.

Application
- Validation of a simple liquid chromatography coupled to tandem mass spectrometry method for the simultaneous determination of tacrolimus, sirolimus, everolimus and cyclosporin A in dried matrix on paper discs: Diese Studie validiert eine durch Zinksulfat-Heptahydrat verbesserte Flüssigkeitschromatographie-Massenspektrometrie-Methode zur Analyse von Immunsuppressiva. Diese Entwicklung stellt einen bedeutenden Fortschritt in der klinischen Diagnostik dar und ermöglicht eine schnellere und zuverlässigere Arzneimittelüberwachung (Bressán et al., 2021).
- Adduct simplification in the analysis of cyanobacterial toxins by matrix-assisted laser desorption/ionization mass spectrometry: Forschung unter Verwendung von Zinksulfat-Heptahydrat in der Matrix-unterstützten Laserdesorptions-/Ionisations-Massenspektrometrie (MALDI) zur Vereinfachung der Analyse von Cyanobakterientoxinen. Diese Studie verbessert das Verständnis von Umweltgiften und zeigt die Rolle von Zinksulfat-Heptahydrat bei der Verbesserung der analytischen Genauigkeit und Effizienz (Howard et al., 2007).

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